It is applicable to stars across the Hertzsprung–Russell (HR) diagram and a powerful technique not only to measure masses, radii, and ages but also directly constrain interior rotation, chemical mixing, and magnetism. This is because a star's self-excited pulsation modes are sensitive to its structure. Asteroseismology generally requires long-duration and high-precision time-series data. The method of forward asteroseismic modeling, which is the statistical comparison of observed pulsation mode frequencies to theoretically predicted pulsation frequencies calculated from a grid of models, provides precise constraints for calibrating various transport phenomena. In this introduction to asteroseismology, we provide an overview of its principles, and the typical data sets and methodologies used to constrain stellar interiors. Finally, we present key highlights of asteroseismic results from across the HR diagram, and conclude with ongoing challenges and future prospects for this ever-expanding field within stellar astrophysics."}],"editor":[{"first_name":"Ilya","full_name":"Mandel, Ilya","last_name":"Mandel"}],"oa":1,"article_processing_charge":"No","date_created":"2026-02-16T10:43:01Z","quality_controlled":"1","citation":{"ista":"Bowman DM, Bugnet LA. 2026.Asteroseismology.

Quadrupolar (ℓ = 2) mixed modes also contain information regarding internal dynamics but are very rarely characterised due to their low amplitude and the challenging identification of adjacent or overlapping rotationally split multiplets affected by near-degeneracy effects. We aim to extend the broadly used asymptotic seismic diagnostics beyond ℓ = 1 mixed modes by developing an analogue asymptotic description of ℓ = 2 mixed modes while explicitly accounting for near-degeneracy effects that distort their rotational multiplets. We have derived a new asymptotic formulation of near-degenerate mixed ℓ = 2 modes that describes off-diagonal terms representing the interaction between modes of adjacent radial orders. This formalism, expressed directly in the mixed-mode basis, provides analytical expressions for the near-degeneracy effects. We implemented the formalism within a global Bayesian mode-fitting framework for a direct fit of all ℓ = 0, 1, 2 modes in the power spectrum density. We were able to asymptotically model the asymmetric rotational splitting present in various radial orders of ℓ = 2 modes observed in young red giant stars without the need for any numerical stellar modelling. We applied our formalism to the Kepler target KIC 7341231, and it yielded core and envelope rotation rates consistent with previous numerical modelling while providing improved constraints from the global and model-independent approach. We also characterised the new target, KIC 8179973, measuring its rotation rate and mixed-mode parameters for the first time. As our framework relies on a direct global fit, it allows for much better precision on the asteroseismic parameters and rotation rate estimates than standard methods, yielding better constraints for rotation inversions. We have placed the first observational constraints on the asymptotic ℓ = 2 mixed-mode parameters (ΔΠ2, q2, and εg, 2), thus paving the way towards the use of asymptotic seismology beyond ℓ = 1 mixed modes."}],"ddc":["520"],"has_accepted_license":"1","DOAJ_listed":"1","article_processing_charge":"No","article_number":"A321","corr_author":"1","day":"01","scopus_import":"1","citation":{"short":"B.R.B.

In particular, the ability of these envelope gravito-inertial modes to couple with those trapped in the radiative interior could open up new opportunities for probing the deep-layer dynamics of solar-type stars. The possibility for such a coupling to occur is particularly favoured among pre-main-sequence (PMS) solar-type stars. Indeed, due to the contraction of the protostellar object, they are able to reach high rotation frequencies before nuclear reactions are ignited and magnetic braking becomes the driving mechanism for their rotational evolution. In this work, we studied the coupling between the envelope inertial waves and the radiative interior g modes in PMS stars, focussing on the case of prograde dipolar modes. We considered the cases of 0.5 M⊙ and 1 M⊙ PMS models, each with three different scenarios of rotational evolution. We show that for stars that have formed with a sufficient amount of angular momentum, this coupling can occur in frequency ranges that are accessible to space-borne photometry, creating inertial dips in the period spacing pattern. Using an asymptotic analysis, we characterised the shape of these inertial dips to show that they depend on rotation and on the stiffness of the convective-radiative interface.","lang":"eng"}],"file_date_updated":"2026-04-07T09:20:02Z","oa":1,"intvolume":"       707","doi":"10.1051/0004-6361/202659309","scopus_import":"1","quality_controlled":"1","citation":{"ama":"Breton SN, Pezzotti C, Mathis S, et al.

Its unusually high excess velocity and active cometary nature make it a key probe of the Galactic population of icy planetesimals. Understanding its origin requires its past trajectory through the Galaxy to be traced and the possible role of stellar encounters to be assessed, both as a potential origin and a perturber to its orbit. We integrated the orbit of 3I/ATLAS backward in time for 10 Myr, together with a sample of Gaia DR3 stars with high-quality astrometry and radial velocities, to identify close passages within 2 pc. We identify 93 nominal encounters, 62 of which are significant at the 2σ level. However, none of these encounters produced any meaningful perturbation. The strongest perturber Gaia DR3 6863591389529611264 at 0.30 pc and with a relative velocity of 35 km s−1, imparted only a velocity change of ∣Δv∣  ≃  5  ×  10−4 km s−1 to the orbit of 3I/ATLAS. Our results indicate that no stellar flybys within the past 10 Myr and 500 pc contained in Gaia DR3 can account for the present trajectory of 3I/ATLAS or be associated with its origin. We further show that 3I/ATLAS is kinematically consistent with a thin-disk population, despite its large peculiar velocity.","lang":"eng"}],"DOAJ_listed":"1","has_accepted_license":"1","article_number":"146","article_processing_charge":"Yes","day":"20","citation":{"apa":"Pérez-Couto, X., Torres Rodriguez, S., Villaver, E., Mustill, A.

Rotation plays an important role in stellar evolution. However, the mechanisms behind the transport of angular momentum in stars at various stages of their evolution are not well understood. To improve our understanding of these processes, it is necessary to measure and validate the internal rotation profiles of stars across different stages of evolution and mass regimes.\r\nAims. Our aim is to constrain the internal rotation profile of the 12-M⊙ β Cep pulsator HD 192575 from the observed pulsational multiplets and the asymmetries of their component frequencies.\r\nMethods. We updated the forward asteroseismic modelling of HD 192575 based on new TESS observations. We inverted the rotation profile from the symmetric part of the splittings and computed the multiplet asymmetries due to the Coriolis force and stellar deformation, which we treated perturbatively. We compared the computed asymmetries with the observed asymmetries.\r\nResults. Our new forward asteroseismic modelling is in agreement with previous results but with increased uncertainties, partially due to increased frequency precision, which required us to relax certain constraints. Ambiguity in the mode identification is the main source of the uncertainty, which also affects the inferred rotation profiles. Almost all acceptable rotation profiles occur in the regime below 0.4 d−1 and favour weak radial differential rotation, with a ratio of core to envelope rotation of less than 2. We find that the quality of the match between the observed and theoretically predicted mode asymmetries is strongly dependent on the mode identification and the internal structure of the star.\r\nConclusions. Our results offer the first detailed rotation inversion for a β Cep pulsator. They show that the rotation profile and the mode asymmetries provide a valuable tool for further constraining the evolutionary properties of HD 192575, and in particular the details of angular momentum transport in massive stars.","lang":"eng"}],"ddc":["520"],"oa":1,"file_date_updated":"2025-09-15T06:58:09Z","article_number":"A5","article_processing_charge":"No","has_accepted_license":"1","quality_controlled":"1","date_created":"2025-09-14T22:01:32Z","citation":{"ama":"Vanlaer V, Bowman DM, Burssens S, et al.

Integrating internal magnetism to the picture appears as the next milestone of detailed asteroseismic studies, for its prime importance on stellar evolution. The inertial dip in prograde dipole modes period-spacing pattern of γ Dors stands out as a unique window on the convective core structure and dynamics. Recent studies have highlighted the dependence of the dip structure on core density stratification, the contrast of the near-core Brunt-Väisälä frequency and rotation rate, as well as the core-to-near-core differential rotation. In addition, the effect of envelope magnetism has been derived on low-frequency magneto-gravito-inertial waves.\r\n\r\nAims. We revisited the inertial dip formation including core and envelope magnetism, and explored the probing power of this feature on dynamo-generated core fields.\r\n\r\nMethods. We considered as a first step a toroidal magnetic field with a bi-layer (core and envelope) Alfvén frequency. This configuration allowed us to revisit the coupling problem using our knowledge on both core magneto-inertial modes and envelope magneto-gravito-inertial modes. Using this configuration, we were able to stay in an analytical framework to exhibit the magnetic effects on the inertial dip shape and location. This configuration allowed a laboratory to be set up that moves us towards the comprehension of magnetic effects on the dip structure.\r\n\r\nResults. We show a shift of the inertial dip towards lower spin parameter values and a thinner dip with increasing core magnetic field’s strength, quite similar to the signature of differential rotation. The magnetic effects become sizeable when the ratio of the magnetic to the Coriolis effects is high enough. We explored the potential degeneracy of the magnetic effects with differential rotation. We studied the detectability of core magnetism, considering both observational constraints on the periods of the modes and potential gravito-inertial mode suppression.","lang":"eng"}]},{"PlanS_conform":"1","OA_type":"gold","project":[{"_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020","grant_number":"101034413","name":"IST-BRIDGE: International postdoctoral program"}],"month":"02","article_type":"original","arxiv":1,"publisher":"Oxford University Press","type":"journal_article","publication_status":"published","oa_version":"Published Version","isi":1,"OA_place":"publisher","publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"ec_funded":1,"_id":"18984","department":[{"_id":"YlGo"},{"_id":"LiBu"}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"Combining REBOUND and MESA: Dynamical evolution of planets orbiting interacting binaries","date_updated":"2025-12-30T07:25:37Z","status":"public","acknowledgement":"We thank the participants of the 2023 Kavli Summer Program in Astrophysics, hosted by the Max Planck Institute for Astrophysics and funded by the Kavli Foundation.

While the tightest-orbit binaries should host the most dynamically stable and long-lived circumbinary planetary systems, they are also the systems that are expected to experience mass transfer, common envelope evolution, or stellar mergers. In this study, we explore the effect of stable non-conservative mass transfer on the dynamical evolution of circumbinary planets. We present a new script that seamlessly integrates binary evolution data from the 1D binary stellar evolution code MESA into the N-body simulation code REBOUND. This integration framework enables a comprehensive examination of the dynamical evolution of circumbinary planets orbiting mass-transferring binaries, while simultaneously accounting for the detailed stellar structure evolution. In addition, we introduce a recalibration method to mitigate numerical errors from updates of binary properties during the system's dynamical evolution. We construct a reference binary model in which a 2.21M⊙ star loses its hydrogen-rich envelope through non-conservative mass transfer to the 1.76M⊙ companion star, creating a 0.38M⊙ subdwarf. We find the tightest stable orbital separation for circumbinary planets to be ≃2.5 times the binary separation after mass transfer. Accounting for tides by using the interior stellar structure, we find that tidal effects become apparent after the rapid mass transfer phase and start to fade away during the latter stage of the slow mass transfer phase. Our research provides a new framework for exploring circumbinary planet dynamics in interacting binary systems."}],"file_date_updated":"2025-12-30T07:24:34Z","oa":1,"article_processing_charge":"Yes","has_accepted_license":"1","DOAJ_listed":"1"},{"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"Constraining differential rotation in γ Doradus stars from the properties of inertial dips","department":[{"_id":"LiBu"}],"date_updated":"2026-02-16T12:09:14Z","isi":1,"OA_place":"publisher","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"_id":"19283","type":"journal_article","publisher":"EDP Sciences","publication_status":"published","oa_version":"Published Version","OA_type":"diamond","project":[{"_id":"914d8549-16d5-11f0-9cad-bbe6324c93a9","name":"Unveiling the mysteries of stellar dynamics: a pioneering journey in magnetoasteroseismology","grant_number":"101165631"}],"month":"02","article_type":"original","abstract":[{"lang":"eng","text":"Context. The presence of dips in the gravity mode period spacing versus period diagram of γ Doradus stars is now well established thanks to recent asteroseismic studies. Such Lorentzian-shaped inertial dips arise from the interaction of gravito-inertial modes in the radiative envelope of intermediate-mass main sequence stars with pure inertial modes in their convective core, and allow us to study stellar internal properties. This window onto stellar internal dynamics is extremely valuable in the context of the understanding of angular-momentum transport inside stars, as it allows us to probe rotation in their core.\r\n\r\nAims. We investigate the signature and the detectability of a differential rotation between the convective core and the near-core region inside γ Doradus stars from the properties of inertial dips.\r\n\r\nMethods. We studied the coupling between gravito-inertial modes in the radiative zone and pure inertial modes in the convective core in the sub-inertial regime, allowing for a two-zone differential rotation from the two sides of the core-to-envelope boundary. We solved the coupling equation numerically and matched the result to an analytical derivation of the Lorentzian dip properties. We then used typical values of measured near-core rotation and buoyancy travel time to infer ranges of parameters for which differential core to near-core rotation would be detectable in current Kepler data.\r\n\r\nResults. We show that increasing the convective core rotation with respect to the near-core rotation leads to a shift of the period of the observed dip to lower periods. In addition, the dip gets deeper and thinner as the convective core rotation increases. We demonstrate that such a signature is detectable in Kepler data, given appropriate dip-parameter ranges and near-core structural properties.\r\n\r\nConclusions. Studying the dip properties in asteroseismic data thus allows us to access core to near-core radial differential rotation and to better understand the transport of angular momentum at convective–radiative interfaces in intermediate-mass main sequence stars."}],"ddc":["520"],"file_date_updated":"2025-03-04T09:57:03Z","oa":1,"article_processing_charge":"Yes","article_number":"A225","has_accepted_license":"1","scopus_import":"1","quality_controlled":"1","date_created":"2025-03-02T23:01:53Z","citation":{"chicago":"Barrault, Lucas, S.

We used 10 independent asteroseismic analysis techniques and anchor our system on fundamental radii derived from Gaia L and spectroscopic Teff. We provide evolutionary state, asteroseismic surface gravity, mass, radius, age, and the data used to derive them for 12,418 stars. This includes 10,036 exceptionally precise measurements, with median fractional uncertainties in \r\nvmax, Δν, mass, radius, and age of 0.6%, 0.6%, 3.8%, 1.8%, and 11.1%, respectively. We provide more limited data for 1624 additional stars that either have lower-quality data or are outside of our primary calibration domain. Using lower red giant branch (RGB) stars, we find a median age for the chemical thick disk of 9.14 ± 0.05(ran) ± 0.9(sys) Gyr with an age dispersion of 1.1 Gyr, consistent with our error model. We calibrate our red clump (RC) mass loss to derive an age consistent with the lower RGB and provide asymptotic GB and RGB ages for luminous stars. We also find a sharp upper-age boundary in the chemical thin disk. We find that scaling relations are precise and accurate on the lower RGB and RC, but they become more model dependent for more luminous giants and break down at the tip of the RGB. We recommend the use of multiple methods, calibration to a fundamental scale, and the use of stellar models to interpret frequency spacings.","lang":"eng"}],"oa":1,"file_date_updated":"2025-03-17T10:40:41Z","file":[{"date_updated":"2025-03-17T10:40:41Z","creator":"dernst","file_id":"19414","relation":"main_file","file_name":"2025_AstrophysicalJourSuppl_Pinsonneault.pdf","success":1,"file_size":4993506,"checksum":"a01a6645c6cb0b5cc75490f3339a2244","content_type":"application/pdf","access_level":"open_access","date_created":"2025-03-17T10:40:41Z"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_published":"2025-02-01T00:00:00Z","volume":276,"author":[{"full_name":"Pinsonneault, Marc H.","last_name":"Pinsonneault","first_name":"Marc H."},{"last_name":"Zinn","full_name":"Zinn, Joel C.","first_name":"Joel C."},{"first_name":"Jamie","full_name":"Tayar, Jamie","last_name":"Tayar"},{"full_name":"Serenelli, Aldo","last_name":"Serenelli","first_name":"Aldo"},{"last_name":"García","full_name":"García, Rafael A.","first_name":"Rafael A."},{"last_name":"Mathur","full_name":"Mathur, Savita","first_name":"Savita"},{"last_name":"Vrard","full_name":"Vrard, Mathieu","first_name":"Mathieu"},{"last_name":"Elsworth","full_name":"Elsworth, Yvonne P.","first_name":"Yvonne P."},{"full_name":"Mosser, Benoit","last_name":"Mosser","first_name":"Benoit"},{"first_name":"Dennis","last_name":"Stello","full_name":"Stello, Dennis"},{"last_name":"Bell","full_name":"Bell, Keaton J.","first_name":"Keaton J."},{"first_name":"Lisa Annabelle","orcid":"0000-0003-0142-4000","full_name":"Bugnet, Lisa Annabelle","last_name":"Bugnet","id":"d9edb345-f866-11ec-9b37-d119b5234501"},{"first_name":"Enrico","full_name":"Corsaro, Enrico","last_name":"Corsaro"},{"full_name":"Gaulme, Patrick","last_name":"Gaulme","first_name":"Patrick"},{"full_name":"Hekker, Saskia","last_name":"Hekker","first_name":"Saskia"},{"full_name":"Hon, Marc","last_name":"Hon","first_name":"Marc"},{"last_name":"Huber","full_name":"Huber, Daniel","first_name":"Daniel"},{"full_name":"Kallinger, Thomas","last_name":"Kallinger","first_name":"Thomas"},{"first_name":"Kaili","full_name":"Cao, Kaili","last_name":"Cao"},{"last_name":"Johnson","full_name":"Johnson, Jennifer A.","first_name":"Jennifer A."},{"first_name":"Bastien","last_name":"Liagre","full_name":"Liagre, Bastien"},{"first_name":"Rachel A.","last_name":"Patton","full_name":"Patton, Rachel A."},{"first_name":"Ângela R.G.","full_name":"Santos, Ângela R.G.","last_name":"Santos"},{"last_name":"Basu","full_name":"Basu, Sarbani","first_name":"Sarbani"},{"last_name":"Beck","full_name":"Beck, Paul G.","first_name":"Paul G."},{"full_name":"Beers, Timothy C.","last_name":"Beers","first_name":"Timothy C."},{"first_name":"William J.","full_name":"Chaplin, William J.","last_name":"Chaplin"},{"full_name":"Cunha, Katia","last_name":"Cunha","first_name":"Katia"},{"full_name":"Frinchaboy, Peter M.","last_name":"Frinchaboy","first_name":"Peter M."},{"last_name":"Girardi","full_name":"Girardi, Léo","first_name":"Léo"},{"full_name":"Godoy-Rivera, Diego","last_name":"Godoy-Rivera","first_name":"Diego"},{"last_name":"Holtzman","full_name":"Holtzman, Jon A.","first_name":"Jon A."},{"first_name":"Henrik","last_name":"Jönsson","full_name":"Jönsson, Henrik"},{"last_name":"Mészáros","full_name":"Mészáros, Szabolcs","first_name":"Szabolcs"},{"first_name":"Claudia","last_name":"Reyes","full_name":"Reyes, Claudia"},{"last_name":"Rix","full_name":"Rix, Hans Walter","first_name":"Hans Walter"},{"first_name":"Matthew","full_name":"Shetrone, Matthew","last_name":"Shetrone"},{"full_name":"Smith, Verne V.","last_name":"Smith","first_name":"Verne V."},{"first_name":"Taylor","full_name":"Spoo, Taylor","last_name":"Spoo"},{"full_name":"Stassun, Keivan G.","last_name":"Stassun","first_name":"Keivan G."},{"first_name":"Ji","full_name":"Wang, Ji","last_name":"Wang"}],"external_id":{"arxiv":["2410.00102"],"isi":["001414132600001"]},"status":"public","acknowledgement":"We thank the anonymous referee for providing constructive comments that improved the paper.

Beta Pictoris is an A-type star that hosts a complex planetary system with two massive gas giants and a prominent debris disc. Variable absorption lines in its stellar spectrum have been interpreted as signatures of exocomets – comet-like bodies transiting the star. Stellar flybys can gravitationally perturb objects in the outer comet reservoir, altering their orbits and potentially injecting them into the inner system, thereby triggering exocomet showers.\r\nAims. We assessed the contribution of stellar flybys to the observed exocomet activity by reconstructing the stellar encounter history of β Pictoris in the past and future.\r\nMethods. We used Gaia DR3 data, supplemented with radial velocities from complementary spectroscopic surveys, to compile a catalogue of stars currently within 80 pc of β Pictoris. Their orbits were integrated backwards and forwards in time in an axisymmetric Galactic potential (via the GALA package) to identify encounters within 2 pc of the system.\r\nResults. We identified 99 416 stars currently within 80 pc of β Pictoris with resolved kinematics. Among these, 49 stars (including the eight components of five binaries) encounter β Pictoris within 2 pc between –1.5 Myr and +2 Myr. For four of the binaries, the centre-of-mass trajectories also pass within 2 pc. We estimated the sample to be more than 60% complete within 0.5 Myr of today.\r\nConclusions. Despite β Pictoris being the eponym of its famous moving group, none of the identified encounters involved its moving group members; all are unrelated field stars. We found no encounter capable of shaping the observed disc structures, although stellar flybys may contribute to the long-term evolution of an Oort Cloud-like structure. Our catalogue constitutes the most complete reconstruction of the β Pictoris encounter history to date and provides a robust foundation for future dynamical simulations.","lang":"eng"}],"ddc":["520"],"doi":"10.1051/0004-6361/202555940","intvolume":"       704","day":"01","citation":{"short":"J.L.

Asymmetries in the observed rotational splittings of a multiplet contain information about the star’s rotation profile and internal magnetic field. Moreover, the frequency regularities of multiplets can be used for mode identification. However, to exploit this information, highly accurate theoretical predictions are needed.\r\n\r\nAims. We aim to quantify the difference in the predicted mode asymmetries between a 1D perturbative method and a 2D method that includes a 2D stellar structure model, which takes rotation into account. We then place these differences between 1D and 2D methods in the context of asteroseismic measurements of internal magnetic fields. We only focus on the asymmetries and not on possible additional frequency peaks that can arise when the magnetic and rotation axis are misaligned.\r\n\r\nMethods. We coupled the 1D pulsation codes GYRE and StORM to the 2D stellar structure code ESTER and compared the oscillation predictions with the results from the 2D TOP pulsation code. We focused on zero-age main-sequence models representative of rotating β Cephei pulsators spinning at up to 20 per cent of the critical Keplerian rotation rate. Specifically, we investigated low-radial-order gravity and pressure modes.\r\n\r\nResults. We find a generally good agreement between the oscillation frequencies resulting from the 1D and 2D pulsation codes. We report differences in predicted mode multiplet asymmetries of mostly below 0.06 d−1. Since the magnetic asymmetries are small compared to the differences in the rotational asymmetries resulting from the 1D and 2D predictions, accurate measurements of the magnetic field are in most cases challenging.\r\n\r\nConclusions. Differences in the predicted mode asymmetries of a rotating star between 1D perturbative methods and 2D non-perturbative methods can greatly hinder accurate measurements of internal magnetic fields in main-sequence pulsators with low-order modes. Nevertheless, reasonably accurate measurements could be possible with npg ≥ 2 modes if the internal rotation is roughly below 10 per cent of the Keplerian critical rotation frequency for (aligned) magnetic fields of the order of a few hundred kilogauss. While the differences between the 1D and 2D frequency predictions are mostly too large for internal magnetic field detections, the rotational asymmetries predicted by StORM are in general accurate enough for asteroseismic modelling of the stellar rotation in main-sequence stars with identified low-order modes."}],"file_date_updated":"2026-01-05T08:36:28Z","oa":1,"article_processing_charge":"No","article_number":"A336","has_accepted_license":"1","DOAJ_listed":"1","scopus_import":"1","date_created":"2026-01-04T23:01:35Z","citation":{"ieee":"J.

Recent observational results from asteroseismic studies show that an important fraction of solar-like stars do not present detectable stochastically excited acoustic oscillations. This non-detectability seems to correlate with a high rotation rate in the convective envelope and a high surface magnetic activity. At the same time, the properties of stellar convection are affected by rotation and magnetism.\r\nAims. We investigate the role of rotation in the excitation of acoustic modes in the convective envelope of solar-like stars, to evaluate its impact on the energy injected in the oscillations.\r\nMethods. We derived theoretical prescriptions for the excitation of acoustic waves in the convective envelope of rotating solar-like stars. We adopted the rotating mixing-length Theory to model the influence of rotation on convection. We used the MESA stellar evolution code and the GYRE stellar oscillation code to estimate the power injected in the oscillations from our theoretical prescriptions.\r\nResults. We demonstrate that the power injected in the acoustic modes is insensitive to rotation if a Gaussian time-correlation function is assumed, while it can decrease by up to 60% for a Lorentzian time-correlation function, for a 20 Ω⊙ rotation rate. We show that the modification of the excitation rate by rotation depends not only on the rotation rate but also on the radial and angular orders of the considered oscillation mode. This result can allow for better constraints on the properties of stellar convection by studying observationally acoustic mode excitation.\r\nConclusions. These results demonstrate how important it is to take into account the modification of stellar convection by rotation when evaluating the amplitude of the stellar oscillations it stochastically excites. They open the path for understanding the large variety of observed acoustic-mode amplitudes at the surface of solar-like stars as a function of surface rotation rates."}],"ddc":["520"],"has_accepted_license":"1","DOAJ_listed":"1","article_processing_charge":"Yes","article_number":"A25","PlanS_conform":"1","OA_type":"gold","article_type":"original","month":"08","oa_version":"Published Version","publication_status":"published","type":"journal_article","publisher":"EDP Sciences","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"OA_place":"publisher","_id":"21252","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"The impact of rotation on the stochastic excitation of stellar acoustic modes in solar-like pulsators","department":[{"_id":"LiBu"}],"date_updated":"2026-02-17T13:10:18Z"},{"day":"21","scopus_import":"1","date_created":"2025-05-04T22:02:30Z","citation":{"ista":"Rauer H et al. 2025.

PLATO will detect small planets (down to <2R Earth) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations from the ground, planets will be characterised for their radius, mass, and age with high accuracy (5%, 10%, 10% for an Earth-Sun combination respectively). PLATO will provide us with a large-scale catalogue of well-characterised small planets up to intermediate orbital periods, relevant for a meaningful comparison to planet formation theories and to better understand planet evolution. It will make possible comparative exoplanetology to place our Solar System planets in a broader context. In parallel, PLATO will study (host) stars using asteroseismology, allowing us to determine the stellar properties with high accuracy, substantially enhancing our knowledge of stellar structure and evolution. The payload instrument consists of 26 cameras with 12cm aperture each. For at least four years, the mission will perform high-precision photometric measurements. Here we review the science objectives, present PLATO‘s target samples and fields, provide an overview of expected core science performance as well as a description of the instrument and the mission profile towards the end of the serial production of the flight cameras. PLATO is scheduled for a launch date end 2026. This overview therefore provides a summary of the mission to the community in preparation of the upcoming operational phases."}],"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","article_number":"26","acknowledgement":"Open Access funding enabled and organized by Projekt DEAL.","status":"public","author":[{"last_name":"Rauer","full_name":"Rauer, Heike","first_name":"Heike"},{"first_name":"Conny","last_name":"Aerts","full_name":"Aerts, Conny"},{"first_name":"Juan","full_name":"Cabrera, Juan","last_name":"Cabrera"},{"first_name":"Magali","last_name":"Deleuil","full_name":"Deleuil, Magali"},{"first_name":"Anders","full_name":"Erikson, Anders","last_name":"Erikson"},{"first_name":"Laurent","full_name":"Gizon, Laurent","last_name":"Gizon"},{"first_name":"Mariejo","full_name":"Goupil, Mariejo","last_name":"Goupil"},{"first_name":"Ana","full_name":"Heras, Ana","last_name":"Heras"},{"full_name":"Walloschek, Thomas","last_name":"Walloschek","first_name":"Thomas"},{"full_name":"Lorenzo-Alvarez, Jose","last_name":"Lorenzo-Alvarez","first_name":"Jose"},{"full_name":"Marliani, Filippo","last_name":"Marliani","first_name":"Filippo"},{"first_name":"César","full_name":"Martin-Garcia, César","last_name":"Martin-Garcia"},{"first_name":"J.

source of information in astronomy. For stars in particular, surface magnetism polarization that can be detected and measured with spectro-polarimetry. Many questions about these surface fields remain unanswered due to a lack of dedicated instruments capable of probing weak and strong surface magnetic fields for the entire mass range of stars, from M-dwarfs (and even substellar objects) to massive O-type stars at different evolutionary stages and metallicities. These questions range from the origin of these fields to their true incidence rate throughout the stellar population and the dependence on metallicity. Magnetic fields, although currently often excluded from stellar evolution models, play an important role in stellar evolution. Connecting the surface fields to internal fields through asteroseismology will instigate a new era of understanding stellar evolution and the transport of angular momentum and chemical elements throughout stellar interiors, also impacting our understanding of star-planet interactions and stellar remnants. Polarimetry is also an under-utilized tool to observationally constrain the mode identification of nonradial oscillations, which lies at the basis of accurate asteroseismic parameter estimation at percentage-level for stellar radii, masses, ages, internal rotation, and magnetic field strengths. Combining strong constraints on mode identification and surface magnetic properties through the acquisition of time-resolved, high-resolution and high-signal-to-noise (S/N) spectro-polarimetry and spectroscopy promises to bring leaps forward in our understanding of stellar structure, particularly when combined with long-term space photometric data from past, current, and future missions."}],"department":[{"_id":"LiBu"}],"title":"Expanding stellar horizons with polarized light","oa":1,"article_processing_charge":"No","date_updated":"2026-04-07T06:00:40Z","article_number":"2512.15170","date_created":"2026-02-17T13:53:50Z","citation":{"ieee":"J.

Red giants are stars that have\r\nevolved off of the main sequence after having completed fusing hydrogen into helium in their\r\ncore. Observational data shows that the cores are rotating significantly slower than models can\r\nrecreate consistently across evolutionary stages. This discrepancy has prompted investigation\r\ninto the efficiency of angular momentum transport mechanisms and mixing processes including\r\nmeridional circulation, shear instability, internal gravity waves, Tayler-Spruit dynamo, fossil\r\nmagnetic fields etc., to explain this behavior.\r\nAnalyzing seismic oscillations in stars, via asteroseismology, is a powerful tool as it is the only\r\nway in which the deep stellar interior can be probed and subsequently characterized; this is\r\npossible as global oscillations modulating the stellar surface are effected by internal processes.\r\nFor red giants, p-modes (pressure modes; resonating through the entire star) and g-modes\r\n(gravity-modes; resonating in the radiative interior) couple to create mixed modes. These\r\nmixed modes give access to the otherwise hidden stellar interior as g-modes couple to p-modes,\r\ndelivering information from the interior to the surface.\r\nInternal magnetic signatures have been observationally confirmed in red giant stars via\r\nasteroseismology and characterized in two ways. One being that dipole mixed modes with\r\nℓ = 1 will display a global asymmetric frequency shift of its azimuthal components; where\r\nthe m = 0 and m = ±1 components of the ℓ = 1 dipole mode will be shifted by two\r\ndifferent power laws, respectively. And the other being a reduced visibility of dipole mixed\r\nmode amplitudes in the power spectra, where stars presenting with this feature are denoted as\r\nsuppressed.\r\nSeveral studies of the suppressed dipole mixed mode amplitudes have been carried out, but thus\r\nfar, no dedicated studies of the asymmetric frequency shifts of suppressed red giants have been\r\nconducted; one reason being that the asymmetric frequency shifts cannot be characterized\r\nwhen the dipole mixed mode amplitudes are severely reduced in many of the suppressed stars.\r\nSincefullysuppressedstarsdonothavedetectablemixed-modestoevaluate, partiallysuppressed\r\nstars, that is, red giant stars presenting with suppressed dipole mixed modes in select parts of\r\ntheir power spectra rather than across the entire spectra, will be the subject of this study as\r\nthe respective mode amplitudes are still visible at high frequencies.\r\nAs such, this study will search for asymmetric frequency shifts on the dipole mixed\r\nmodes of partially suppressed red giant stars; the aim here is to investigate if both\r\nmode suppression and magnetic shifting of dipole mixed modes occur simultaneously.\r\nThisstudywillbeconductedbycreatingapipelinetoestimatepriorsofasteroseismicparameters,\r\nuse the priors to model the power spectra with the stellar modeling code sloscillations_ISTA,\r\nand perform a Bayesian fit of the parameters with the simulated data on the star KIC 6975038,\r\na target with partially suppressed dipolar mode amplitudes identified in the literature, to fit its\r\nmagnetic parameters. I present a novel method to model the stellar power spectra of\r\npartially suppressed red giants by application of a sigmoid profile to the ℓ= 1 dipolar\r\nmode component of the spectra. With the results of this study I aim at constraining\r\nthe cause of this partial dipole mode amplitude suppression, allowing for more detailed\r\nstudies regarding their astrophysical nature. Furthermore, the long term hope for the method\r\nused in this study will be to expand the sample of partially suppressed red giants and fit their\r\nasteroseismic parameters accordingly.","lang":"eng"}],"author":[{"full_name":"Smith, Kanah","last_name":"Smith","id":"7703505d-3211-11ee-a6a9-a2ab9d936c15","first_name":"Kanah"}],"file":[{"creator":"ksmith","file_id":"20434","relation":"source_file","date_updated":"2025-10-08T09:45:33Z","checksum":"80d241d11b69af771c1fab0998be4f19","content_type":"application/zip","access_level":"closed","date_created":"2025-10-08T08:01:42Z","file_name":"2025_Smith_Kanah_Thesis.zip","file_size":8263624},{"date_updated":"2025-10-09T14:38:57Z","creator":"ksmith","file_id":"20439","relation":"main_file","success":1,"file_name":"2025_Smith_Kanah_Thesis.pdf","file_size":9748339,"checksum":"13cb48cc98e00fdfe32f3ff66f17aa26","content_type":"application/pdf","access_level":"open_access","date_created":"2025-10-09T14:38:57Z"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_published":"2025-10-08T00:00:00Z","acknowledgement":"I would like to give thanks to myself for my hard work on this document.

The properties of these modes are sensitive to both core rotation and magnetic fields. While asteroseismic studies of the former have been done on a large scale, studies of the latter are currently limited to tens of stars. We aim to produce the first large catalogue of both magnetic and rotational perturbations. We jointly constrain these parameters by devising an automated method for fitting the power spectra directly. We successfully apply the method to 302 low-luminosity red giants. We find a clear bimodality in core rotation rate. The primary peak is at δνrot = 0.32 μHz, and the secondary at δνrot = 0.47 μHz. Combining our results with literature values, we find that the percentage of stars rotating much more rapidly than the population average increases with evolutionary state. We measure magnetic splittings of 2σ significance in 23 stars. While the most extreme magnetic splitting values appear in stars with masses > 1.1M⊙, implying they formerly hosted a convective core, a small but statistically significant magnetic splitting is measured at lower masses. Asymmetry between the frequencies of a rotationally split multiplet has previously been used to diagnose the presence of a magnetic perturbation. We find that of the stars with a significant detection of magnetic perturbation, 43\\% do not show strong asymmetry. We find no strong evidence of correlation between the rotation and magnetic parameters.","lang":"eng"}],"ddc":["520"],"doi":"10.1093/mnras/stae2053","intvolume":"       534","day":"01","citation":{"short":"E.J.

However, current measurements, which are limited to dipolar (ℓ = 1) mixed modes, do not properly constrain the topology of magnetic fields due to degeneracies on the observed magnetic field signature on such ℓ = 1 mode frequencies. Efforts focused toward unambiguous detections of magnetic field configurations are now key to better understand angular momentum transport in stars. We investigated the detectability of complex magnetic field topologies (such as the ones observed at the surface of stars with a radiative envelope with spectropolarimetry) inside the radiative interior of red giants. We focused on a field composed of a combination of a dipole and a quadrupole (quadrudipole) and on an offset field. We explored the potential of probing such magnetic field topologies from a combined measurement of magnetic signatures on ℓ = 1 and quadrupolar (ℓ = 2) mixed mode oscillation frequencies. We first derived the asymptotic theoretical formalism for computing the asymmetric signature in the frequency pattern for ℓ = 2 modes due to a quadrudipole magnetic field. To access asymmetry parameters for more complex magnetic field topologies, we numerically performed a grid search over the parameter space to map the degeneracy of the signatures of given topologies. We demonstrate the crucial role played by ℓ = 2 mixed modes in accessing internal magnetic fields with a quadrupolar component. The degeneracy of the quadrudipole compared to pure dipolar fields is lifted when considering magnetic asymmetries in both ℓ = 1 and ℓ = 2 mode frequencies. In addition to the analytical derivation for the quadrudipole, we present the prospect for complex magnetic field inversions using magnetic sensitivity kernels from standard perturbation analysis for forward modeling. Using this method, we explored the detectability of offset magnetic fields from ℓ = 1 and ℓ = 2 frequencies and demonstrate that offset fields may be mistaken for weak and centered magnetic fields, resulting in underestimating the magnetic field strength in stellar cores. We emphasize the need to characterize ℓ = 2 mixed-mode frequencies, (along with the currently characterized ℓ = 1 mixed modes), to unveil the higher-order components of the geometry of buried magnetic fields and to better constrain angular momentum transport inside stars."}],"file_date_updated":"2024-11-11T09:01:11Z","oa":1,"article_processing_charge":"No","article_number":"A217","has_accepted_license":"1","scopus_import":"1","citation":{"ama":"Das SB, Einramhof L, Bugnet LA.

This paper is the first of a series dedicated to the preparation of the analysis of stellar surface rotation and photospheric activity with the near-future PLATO data. We describe in this work the strategy that will be implemented in the PLATO pipeline to measure stellar surface rotation, photometric activity, and long-term modulations. The algorithms are applied on both noise-free and noisy simulations of solar-type stars, which include activity cycles, latitudinal differential rotation, and spot evolution. PLATO simulated systematics are included in the noisy light curves. We show that surface rotation periods can be recovered with confidence for most of the stars with only six months of observations and that the recovery rate of the analysis significantly improves as additional observations are collected. This means that the first PLATO data release will already provide a substantial set of measurements for this quantity, with a significant refinement on their quality as the instrument obtains longer light curves. Measuring the Schwabe-like magnetic activity cycle during the mission will require that the same field be observed over a significant timescale (more than four years). Nevertheless, PLATO will provide a vast and robust sample of solar-type stars with constraints on the activity-cycle length. Such a sample is lacking from previous missions dedicated to space photometry."}],"oa":1,"file_date_updated":"2025-01-27T13:18:41Z","article_number":"A229","article_processing_charge":"No","has_accepted_license":"1","OA_type":"hybrid","month":"09","article_type":"original","arxiv":1,"type":"journal_article","publication_status":"published","publisher":"EDP Sciences","oa_version":"Published Version","OA_place":"publisher","isi":1,"publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"_id":"18904","title":"Measuring stellar surface rotation and activity with the PLATO mission.
