We use a point-scale physically based energy balance (EB) model and an enhanced Temperature-Index (ETI) model that calculates melt rates only as a function of air temperature and net shortwave radiation. At all sites, the largest energy inputs are net shortwave and incoming longwave radiation, which are controlled by surface albedo and elevation, respectively. Turbulent fluxes cancel each other out at the lower sites, but as elevation increases, cold, dry and wind-exposed conditions increase the magnitude of negative latent heat fluxes, associated with large surface sublimation rates. In midsummer (January), ablation rates vary from 67.9 mm w.e. d−1 at the lowest site (∼100% corresponding to melt), to 2.3 mm w.e. d−1 at the highest site (>85% corresponding to surface sublimation). At low-elevation, low-albedo, melt-dominated sites, the ETI model correctly reproduces melt using a large range of possible parameters, but both the performance and parameter transferability decrease with elevation for two main reasons: (i) the air temperature threshold approach for melt onset does not capture the diurnal variability of melt in cold and strong irradiated environments and (ii) energy losses decrease the correlation between melt and net shortwave radiation. We summarize our results by means of an elevation profile of ablation components that can be used as reference in future studies of glacier ablation in the semiarid Andes.","lang":"eng"}],"citation":{"ama":"Ayala A, Pellicciotti F, MacDonell S, McPhee J, Burlando P.

We analyse 172 Landsat TM/ETM+ scenes for the period 1999–2013 to identify thawed supraglacial ponds for the debris-covered tongues of five glaciers in the Langtang Valley of Nepal. We apply an advanced atmospheric correction routine (Landcor/6S) and use band ratio and image morphological techniques to identify ponds and validate our results with 2.5 m Cartosat-1 observations. We then characterize the spatial, seasonal and interannual patterns of ponds. We find high variability in pond incidence between glaciers (May–October means of 0.08–1.69% of debris area), with ponds most frequent in zones of low surface gradient and velocity. The ponds show pronounced seasonality, appearing in the pre-monsoon as snow melts, peaking at the monsoon onset at 2% of debris-covered area, then declining in the post-monsoon as ponds drain or freeze. Ponds are highly recurrent and persistent, with 40.5% of pond locations occurring for multiple years. Rather than a trend in pond cover over the study period, we find high interannual variability for each glacier after controlling for seasonality."}],"article_type":"original","date_updated":"2023-02-24T11:38:31Z","article_processing_charge":"No","intvolume":"        63","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Spatial, seasonal and interannual variability of supraglacial ponds in the Langtang Valley of Nepal, 1999–2013","publisher":"Cambridge University Press","doi":"10.1017/jog.2016.120","publication_status":"published","status":"public","day":"01","type":"journal_article","scopus_import":"1","page":"88-105","publication":"Journal of Glaciology"},{"has_accepted_license":"1","main_file_link":[{"open_access":"1","url":"https://vsc.ac.at/fileadmin/user_upload/vsc/conferences/ahpc17/BOOKLET_AHPC17.pdf"}],"type":"conference_abstract","month":"03","page":"28","file":[{"checksum":"7bcc499479d4f4c5ce6c0071c24ca6c6","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_id":"12969","file_name":"2017_AHPC_Schloegl.pdf","success":1,"date_created":"2023-05-16T07:20:50Z","creator":"dernst","date_updated":"2023-05-16T07:20:50Z","file_size":1005486}],"oa_version":"Published Version","publication":"AHPC17 – Austrian HPC Meeting 2017","citation":{"ieee":"A.

Examples include improved ferroelectrics for memory devices and materials that host Majorana zero modes for quantum computing1,2. Although inversion symmetry is naturally broken in several crystalline environments, such as at surfaces and interfaces, maximizing the influence of this effect on the electronic states of interest remains a challenge. Here we present a mechanism for realizing a much larger coupling of inversion-symmetry breaking to itinerant surface electrons than is typically achieved. The key element is a pronounced asymmetry of surface hopping energies—that is, a kinetic-energy-coupled inversion-symmetry breaking, the energy scale of which is a substantial fraction of the bandwidth. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate that such a strong inversion-symmetry breaking, when combined with spin–orbit interactions, can mediate Rashba-like3,4 spin splittings that are much larger than would typically be expected. The energy scale of the inversion-symmetry breaking that we achieve is so large that the spin splitting in the CoO2- and RhO2-derived surface states of delafossite oxides becomes controlled by the full atomic spin–orbit coupling of the 3d and 4d transition metals, resulting in some of the largest known Rashba-like3,4 spin splittings. The core structural building blocks that facilitate the bandwidth-scaled inversion-symmetry breaking are common to numerous materials. Our findings therefore provide opportunities for creating spin-textured states and suggest routes to interfacial control of inversion-symmetry breaking in designer heterostructures of oxides and other material classes."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1708.03887"}],"month":"09","language":[{"iso":"eng"}],"date_created":"2025-06-10T09:13:08Z","extern":"1","quality_controlled":"1","issue":"7673","oa":1,"year":"2017","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Springer Nature","title":"Maximal Rashba-like spin splitting via kinetic-energy-coupled inversion-symmetry breaking","article_processing_charge":"No","pmid":1,"intvolume":"       549","arxiv":1,"date_updated":"2025-06-10T11:55:09Z","article_type":"letter_note","page":"492-496","publication":"Nature","type":"journal_article","scopus_import":"1","day":"28","publication_status":"published","status":"public","doi":"10.1038/nature23898"},{"publication":"Physical Review B","type":"journal_article","scopus_import":"1","publication_status":"published","day":"31","status":"public","doi":"10.1103/physrevb.96.075163","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","title":"Quasi-two-dimensional Fermi surface topography of the delafossite PdRhO2","article_processing_charge":"No","intvolume":"        96","arxiv":1,"article_type":"original","date_updated":"2025-06-10T11:59:05Z","oa_version":"Preprint","OA_type":"green","abstract":[{"text":"We report on a combined study of the de Haas-van Alphen effect and angle-resolved photoemission spectroscopy on single crystals of the metallic delafossite rounded off by ab initio band structure calculations.

It was originally proposed to model ferromagnetic interactions in statistical physics and is now widely used to model spatial processes in many areas such as ecology, sociology, and genetics, usually without testing its goodness-of-fit. Here, we propose an exact goodness-of-fit test for the finite-lattice Ising model. The theory of Markov bases has been developed in algebraic statistics for exact goodness-of-fit testing using a Monte Carlo approach. However, this beautiful theory has fallen short of its promise for applications, because finding a Markov basis is usually computationally intractable. We develop a Monte Carlo method for exact goodness-of-fit testing for the Ising model which avoids computing a Markov basis and also leads to a better connectivity of the Markov chain and hence to a faster convergence. We show how this method can be applied to analyze the spatial organization of receptors on the cell membrane.","lang":"eng"}],"oa_version":"Preprint","oa":1,"year":"2017","issue":"2","quality_controlled":"1","date_created":"2018-12-11T11:55:13Z","language":[{"iso":"eng"}],"_id":"2016","author":[{"last_name":"Martin Del Campo Sanchez","first_name":"Abraham","full_name":"Martin Del Campo Sanchez, Abraham"},{"last_name":"Cepeda Humerez","full_name":"Cepeda Humerez, Sarah A","first_name":"Sarah A","id":"3DEE19A4-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Caroline","id":"49ADD78E-F248-11E8-B48F-1D18A9856A87","full_name":"Uhler, Caroline","orcid":"0000-0002-7008-0216","last_name":"Uhler"}],"related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"6473"}]},"department":[{"_id":"GaTk"}],"date_published":"2017-06-01T00:00:00Z","publication_identifier":{"issn":["03036898"]},"external_id":{"arxiv":["1410.1242"],"isi":["000400985000001"]},"volume":44},{"related_material":{"record":[{"id":"457","status":"public","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","status":"public","id":"561"},{"id":"1243","status":"public","relation":"part_of_dissertation"}]},"_id":"202","author":[{"full_name":"Pleska, Maros","first_name":"Maros","id":"4569785E-F248-11E8-B48F-1D18A9856A87","last_name":"Pleska","orcid":"0000-0001-7460-7479"}],"supervisor":[{"first_name":"Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","full_name":"Guet, Calin C","orcid":"0000-0001-6220-2052","last_name":"Guet"}],"publication_identifier":{"issn":["2663-337X"]},"department":[{"_id":"CaGu"}],"pubrep_id":"916","date_published":"2017-10-01T00:00:00Z","file":[{"checksum":"33cfb59674e91f82e3738396d3fb3776","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"4710","file_name":"IST-2018-916-v1+3_2017_Pleska_Maros_Thesis.pdf","creator":"system","date_created":"2018-12-12T10:08:48Z","file_size":18569590,"date_updated":"2020-07-14T12:45:24Z"},{"creator":"dernst","date_created":"2019-04-05T08:33:14Z","file_size":2801649,"date_updated":"2020-07-14T12:45:24Z","relation":"source_file","checksum":"dcc239968decb233e7f98cf1083d8c26","access_level":"closed","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","file_id":"6204","file_name":"2017_Pleska_Maros_Thesis.docx"}],"oa_version":"Published Version","abstract":[{"lang":"eng","text":"Restriction-modification (RM) represents the simplest and possibly the most widespread mechanism of self/non-self discrimination in nature. In order to provide bacteria with immunity against bacteriophages and other parasitic genetic elements, RM systems rely on a balance between two enzymes: the restriction enzyme, which cleaves non-self DNA at specific restriction sites, and the modification enzyme, which tags the host’s DNA as self and thus protects it from cleavage. In this thesis, I use population and single-cell level experiments in combination with mathematical modeling to study different aspects of the interplay between RM systems, bacteria and bacteriophages. First, I analyze how mutations in phage restriction sites affect the probability of phage escape – an inherently stochastic process, during which phages accidently get modified instead of restricted. Next, I use single-cell experiments to show that RM systems can, with a low probability, attack the genome of their bacterial host and that this primitive form of autoimmunity leads to a tradeoff between the evolutionary cost and benefit of RM systems. Finally, I investigate the nature of interactions between bacteria, RM systems and temperate bacteriophages to find that, as a consequence of phage escape and its impact on population dynamics, RM systems can promote acquisition of symbiotic bacteriophages, rather than limit it. The results presented here uncover new fundamental biological properties of RM systems and highlight their importance in the ecology and evolution of bacteria, bacteriophages and their interactions."}],"citation":{"chicago":"Pleska, Maros. “Biology of Restriction-Modification Systems at the Single-Cell and Population Level.” Institute of Science and Technology Austria, 2017. <a href=\"https://doi.org/10.15479/AT:ISTA:th_916\">https://doi.org/10.15479/AT:ISTA:th_916</a>.","apa":"Pleska, M.

The hypothalamus and mesolimbic dopamine system are key mediators of these behaviors, yet regulation of appetitive and consummatory behaviors outside of these regions is poorly understood. The central nucleus of the amygdala (CeA) has been implicated in feeding and reward, but the neurons and circuit mechanisms that positively regulate these behaviors remain unclear. Here, we defined the neuronal mechanisms by which CeA neurons promote food consumption. Using in vivo activity manipulations and Ca2+ imaging in mice, we found that GABAergic serotonin receptor 2a (Htr2a)-expressing CeA neurons modulate food consumption, promote positive reinforcement and are active in vivo during eating. We demonstrated electrophysiologically, anatomically and behaviorally that intra-CeA and long-range circuit mechanisms underlie these behaviors. Finally, we showed that CeAHtr2a neurons receive inputs from feeding-relevant brain regions. Our results illustrate how defined CeA neural circuits positively regulate food consumption.","lang":"eng"}],"OA_type":"green","oa_version":"Preprint","month":"10","main_file_link":[{"url":"https://doi.org/10.1101/145375","open_access":"1"}],"quality_controlled":"1","extern":"1","language":[{"iso":"eng"}],"date_created":"2025-04-03T12:30:57Z","oa":1,"year":"2017","issue":"10","title":"Central amygdala circuits modulate food consumption through a positive-valence mechanism","publisher":"Springer Nature","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1,"intvolume":"        20","article_processing_charge":"No","date_updated":"2025-07-10T11:51:42Z","article_type":"original","publication":"Nature Neuroscience","page":"1384-1394","scopus_import":"1","type":"journal_article","day":"01","publication_status":"published","status":"public","doi":"10.1038/nn.4623"},{"type":"journal_article","scopus_import":"1","publication":"eLife","doi":"10.7554/elife.26163","publication_status":"published","day":"01","status":"public","article_processing_charge":"Yes","pmid":1,"intvolume":"         6","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"eLife Sciences Publications","title":"Structural dynamics of RbmA governs plasticity of Vibrio cholerae biofilms","date_updated":"2024-03-25T12:22:54Z","article_type":"original","main_file_link":[{"open_access":"1","url":"https://doi.org/10.7554/eLife.26163"}],"month":"08","oa_version":"Published Version","abstract":[{"lang":"eng","text":"Biofilm formation is critical for the infection cycle of Vibrio cholerae.

The structural switch in FnIII-1 regulates interactions in trans with the FnIII-2 domain, leading to open (monomeric) or closed (dimeric) interfaces.

Here, we report the discovery of two distinct conformational states that slowly exchange within the dynamic TAD to control timing. This binary switch results from cis/trans isomerization about a highly conserved Trp-Pro imide bond in a region of the TAD that is required for normal circadian timekeeping. Both cis and trans isomers interact with transcriptional regulators, suggesting that isomerization could serve a role in assembling regulatory complexes in vivo. Toward this end, we show that locking the switch into the trans isomer leads to shortened circadian periods. Furthermore, isomerization is regulated by the cyclophilin family of peptidyl-prolyl isomerases, highlighting the potential for regulation of BMAL1 protein dynamics in period determination."}],"citation":{"ieee":"C.

In cyanobacteria, timing is generated by a posttranslational clock consisting of KaiA, KaiB, and KaiC proteins and a set of output signaling proteins, SasA and CikA, which transduce this rhythm to control gene expression. Here, we describe crystal and nuclear magnetic resonance structures of KaiB-KaiC,KaiA-KaiB-KaiC, and CikA-KaiB complexes. They reveal how the metamorphic properties of KaiB, a protein that adopts two distinct folds, and the post–adenosine triphosphate hydrolysis state of KaiC create a hub around which nighttime signaling events revolve, including inactivation of KaiA and reciprocal regulation of the mutually antagonistic signaling proteins, SasA and CikA.","lang":"eng"}],"publication_identifier":{"eissn":["1095-9203"],"issn":["0036-8075"]},"date_published":"2017-03-17T00:00:00Z","keyword":["Multidisciplinary"],"volume":355,"_id":"15156","author":[{"last_name":"Tseng","first_name":"Roger","full_name":"Tseng, Roger"},{"full_name":"Goularte, Nicolette F.","first_name":"Nicolette F.","last_name":"Goularte"},{"last_name":"Chavan","full_name":"Chavan, Archana","first_name":"Archana"},{"last_name":"Luu","full_name":"Luu, Jansen","first_name":"Jansen"},{"first_name":"Susan E.","full_name":"Cohen, Susan E.","last_name":"Cohen"},{"full_name":"Chang, Yong-Gang","first_name":"Yong-Gang","last_name":"Chang"},{"first_name":"Joel","full_name":"Heisler, Joel","last_name":"Heisler"},{"last_name":"Li","full_name":"Li, Sheng","first_name":"Sheng"},{"last_name":"Michael","first_name":"Alicia Kathleen","id":"6437c950-2a03-11ee-914d-d6476dd7b75c","full_name":"Michael, Alicia Kathleen"},{"first_name":"Sarvind","full_name":"Tripathi, Sarvind","last_name":"Tripathi"},{"last_name":"Golden","first_name":"Susan S.","full_name":"Golden, Susan S."},{"last_name":"LiWang","first_name":"Andy","full_name":"LiWang, Andy"},{"first_name":"Carrie L.","full_name":"Partch, Carrie L.","last_name":"Partch"}],"doi":"10.1126/science.aag2516","publication_status":"published","day":"17","status":"public","type":"journal_article","scopus_import":"1","page":"1174-1180","publication":"Science","article_type":"original","date_updated":"2024-03-25T12:16:44Z","article_processing_charge":"No","intvolume":"       355","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Structural basis of the day-night transition in a bacterial circadian clock","publisher":"American Association for the Advancement of Science"},{"issue":"7","year":"2017","oa":1,"extern":"1","language":[{"iso":"eng"}],"date_created":"2024-03-21T07:56:50Z","quality_controlled":"1","main_file_link":[{"url":"https://doi.org/10.1073/pnas.1615310114","open_access":"1"}],"month":"01","oa_version":"Published Version","citation":{"short":"A.K.

Precise control of CLOCK:BMAL1 activity by coactivators and repressors establishes the ∼24-h periodicity of gene expression. Formation of a repressive complex, defined by the core clock proteins cryptochrome 1 (CRY1):CLOCK:BMAL1, plays an important role controlling the switch from repression to activation each day. Here we show that CRY1 binds directly to the PAS domain core of CLOCK:BMAL1, driven primarily by interaction with the CLOCK PAS-B domain. Integrative modeling and solution X-ray scattering studies unambiguously position a key loop of the CLOCK PAS-B domain in the secondary pocket of CRY1, analogous to the antenna chromophore-binding pocket of photolyase. CRY1 docks onto the transcription factor alongside the PAS domains, extending above the DNA-binding bHLH domain. Single point mutations at the interface on either CRY1 or CLOCK disrupt formation of the ternary complex, highlighting the importance of this interface for direct regulation of CLOCK:BMAL1 activity by CRY1.","lang":"eng"}],"publication_identifier":{"eissn":["1091-6490"],"issn":["0027-8424"]},"date_published":"2017-01-31T00:00:00Z","keyword":["Multidisciplinary"],"external_id":{"pmid":["28143926"]},"volume":114,"author":[{"full_name":"Michael, Alicia Kathleen","first_name":"Alicia Kathleen","id":"6437c950-2a03-11ee-914d-d6476dd7b75c","last_name":"Michael"},{"first_name":"Jennifer L.","full_name":"Fribourgh, Jennifer L.","last_name":"Fribourgh"},{"full_name":"Chelliah, Yogarany","first_name":"Yogarany","last_name":"Chelliah"},{"last_name":"Sandate","full_name":"Sandate, Colby R.","first_name":"Colby R."},{"last_name":"Hura","first_name":"Greg L.","full_name":"Hura, Greg L."},{"first_name":"Dina","full_name":"Schneidman-Duhovny, Dina","last_name":"Schneidman-Duhovny"},{"last_name":"Tripathi","first_name":"Sarvind M.","full_name":"Tripathi, Sarvind M."},{"last_name":"Takahashi","first_name":"Joseph S.","full_name":"Takahashi, Joseph S."},{"full_name":"Partch, Carrie L.","first_name":"Carrie L.","last_name":"Partch"}],"_id":"15157","doi":"10.1073/pnas.1615310114","publication_status":"published","day":"31","status":"public","type":"journal_article","scopus_import":"1","page":"1560-1565","publication":"Proceedings of the National Academy of Sciences","date_updated":"2024-03-25T12:12:23Z","article_type":"original","article_processing_charge":"No","intvolume":"       114","pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Formation of a repressive complex in the mammalian circadian clock is mediated by the secondary pocket of CRY1","publisher":"Proceedings of the National Academy of Sciences"},{"volume":93,"keyword":["Physical and Theoretical Chemistry","General Medicine","Biochemistry"],"publication_identifier":{"issn":["0031-8655"],"eissn":["1751-1097"]},"date_published":"2017-02-01T00:00:00Z","author":[{"last_name":"Michael","id":"6437c950-2a03-11ee-914d-d6476dd7b75c","first_name":"Alicia Kathleen","full_name":"Michael, Alicia Kathleen"},{"last_name":"Fribourgh","first_name":"Jennifer L.","full_name":"Fribourgh, Jennifer L."},{"first_name":"Russell N.","full_name":"Van Gelder, Russell N.","last_name":"Van Gelder"},{"last_name":"Partch","full_name":"Partch, Carrie L.","first_name":"Carrie L."}],"_id":"15158","language":[{"iso":"eng"}],"date_created":"2024-03-21T07:57:18Z","extern":"1","quality_controlled":"1","issue":"1","year":"2017","oa":1,"oa_version":"Published Version","citation":{"ama":"Michael AK, Fribourgh JL, Van Gelder RN, Partch CL.

There are two types of cryptochromes in the animal kingdom: <jats:italic>Drosophila</jats:italic>‐like CRYs that act as nonvisual photopigments linking circadian rhythms to the environmental light/dark cycle, and vertebrate‐like CRYs that do not appear to sense light directly, but control the generation of circadian rhythms by acting as transcriptional repressors. Some animals have both types of CRYs, while others possess only one. Cryptochromes have two domains, the photolyase homology region (PHR) and an extended, intrinsically disordered C‐terminus. While all animal CRYs share a high degree of sequence and structural homology in their PHR domains, the C‐termini are divergent in both length and sequence identity. Recently, cryptochrome function has been shown to extend beyond its pivotal role in circadian clocks, participating in regulation of the DNA damage response, cancer progression and glucocorticoid signaling, as well as being implicated as possible magnetoreceptors. In this review, we provide a historical perspective on the discovery of animal cryptochromes, examine similarities and differences of the two types of animal cryptochromes and explore some of the divergent roles for this class of proteins."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1111/php.12677"}],"month":"02","date_updated":"2024-03-25T12:09:21Z","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Wiley","title":"Animal cryptochromes: Divergent roles in light perception, circadian timekeeping and beyond","article_processing_charge":"No","intvolume":"        93","publication_status":"published","day":"01","status":"public","doi":"10.1111/php.12677","page":"128-140","publication":"Photochemistry and Photobiology","type":"journal_article","scopus_import":"1"},{"arxiv":1,"date_updated":"2024-04-08T07:04:10Z","article_type":"original","publisher":"Oxford University Press","title":"The onset of convective coupling and freezing in the white dwarfs of 47 Tucanae","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"       474","article_processing_charge":"No","day":"24","status":"public","publication_status":"published","doi":"10.1093/mnras/stx2759","publication":"Monthly Notices of the Royal Astronomical Society","page":"677-682","scopus_import":"1","type":"journal_article","external_id":{"arxiv":["1709.08097"]},"volume":474,"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"date_published":"2017-10-24T00:00:00Z","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"author":[{"full_name":"Obertas, Alysa","first_name":"Alysa","last_name":"Obertas"},{"full_name":"Caiazzo, Ilaria","first_name":"Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","last_name":"Caiazzo","orcid":"0000-0002-4770-5388"},{"last_name":"Heyl","full_name":"Heyl, Jeremy","first_name":"Jeremy"},{"last_name":"Richer","full_name":"Richer, Harvey","first_name":"Harvey"},{"full_name":"Kalirai, Jason","first_name":"Jason","last_name":"Kalirai"},{"first_name":"Pier-Emmanuel","full_name":"Tremblay, Pier-Emmanuel","last_name":"Tremblay"}],"_id":"15239","quality_controlled":"1","language":[{"iso":"eng"}],"date_created":"2024-03-26T10:40:05Z","extern":"1","year":"2017","oa":1,"issue":"1","abstract":[{"lang":"eng","text":"Using images from the Hubble Space Telescope Advanced Camera for Surveys, we measure the rate of cooling of white dwarfs in the globular cluster 47 Tucanae and compare it to modelled cooling curves.

We confront analytic models of the globular cluster with the observed stellar proper motions that probe along the main sequence from just above 0.8–0.1M⊙ as well as white dwarfs younger than 1 Gyr. One field lies just beyond the half-light radius where dynamical models (e.g., lowered Maxwellian distributions) make robust predictions for the stellar proper motions. The observed proper motions in this outer field show evidence for anisotropy in the velocity distribution as well as skewness; the latter is evidence of rotation. The measured velocity dispersions and surface brightness distributions agree in detail with a rotating anisotropic model of the stellar distribution function with mild dependence of the proper-motion dispersion on mass. However, the best-fitting models underpredict the rotation and skewness of the stellar velocities. In the second field, centered on the core of the cluster, the mass segregation in proper motion is much stronger. Nevertheless the model developed in the outer field can be extended inward by taking this mass segregation into account in a heuristic fashion. The proper motions of the main-sequence stars yield a mass estimate of the cluster of \r\n at a distance of 4.7 kpc. By comparing the proper motions of a sample of giant and subgiant stars with the observed radial velocities we estimate the distance to the cluster kinematically to be 4.29 ± 0.47 kpc."}],"citation":{"ama":"Heyl J, Caiazzo I, Richer H, Anderson J, Kalirai J, Parada J.

Stellar evolution models predict that the mass-loss on the AGB will be pulsed; furthermore, observations indicate that the bulk of the mass-loss occurs on the AGB. In this case, if the progenitors of the white dwarfs had remnants of planetary formation like the Sun’s Oort cloud or the Kuiper Belt and a planet lying within that cloud or nearby, we find that up to 2 per cent of the planetesimals will fall either into planet-crossing orbits or into chaotic regions after the mass-loss, depending on the location and mass of the planet (from Mars to Neptune). This yields a sufficient mass of comets that can be scattered towards the star, form a debris disc and pollute the atmosphere.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1702.07682"}],"month":"05","extern":"1","date_created":"2024-03-26T10:40:45Z","language":[{"iso":"eng"}],"quality_controlled":"1","issue":"3","year":"2017","oa":1,"author":[{"full_name":"Caiazzo, Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria","last_name":"Caiazzo","orcid":"0000-0002-4770-5388"},{"first_name":"Jeremy S.","full_name":"Heyl, Jeremy S.","last_name":"Heyl"}],"_id":"15241","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"external_id":{"arxiv":["1702.07682"]},"volume":469,"publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"date_published":"2017-05-01T00:00:00Z"},{"type":"journal_article","scopus_import":"1","page":"1856-1872","publication":"Monthly Notices of the Royal Astronomical Society","doi":"10.1093/mnras/stx1727","publication_status":"published","day":"13","status":"public","article_processing_charge":"No","intvolume":"       471","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Magnetar giant flare high-energy emission","publisher":"Oxford University Press","article_type":"original","date_updated":"2024-04-08T07:05:47Z","arxiv":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1707.02922"}],"month":"07","oa_version":"Preprint","citation":{"short":"C.

It has been conjectured that this emission might arise via inverse Compton scattering in a highly extended corona generated by super-Eddington outflows high up in the magnetosphere. In this paper, we undertake a detailed examination of this model. We investigate the properties of the required scatterers, and whether the mechanism is consistent with the degree of pulsed emission observed in the tail of the GF. We conclude that the mechanism is consistent with current data, although the origin of the scattering population remains an open question. We propose an alternative picture in which the emission is closer to that star and is dominated by synchrotron radiation. The Reuven Ramaty High Energy Solar Spectroscopic Imager observations of the 2004 December flare modestly favour this latter picture. We assess the prospects for the Fermi Gamma-ray Space Telescope to detect and characterize a similar high-energy component in a future GF. Such a detection should help to resolve some of the outstanding issues."}],"issue":"2","oa":1,"year":"2017","extern":"1","date_created":"2024-03-26T10:41:24Z","language":[{"iso":"eng"}],"quality_controlled":"1","author":[{"last_name":"Elenbaas","full_name":"Elenbaas, C.","first_name":"C."},{"first_name":"D.","full_name":"Huppenkothen, D.","last_name":"Huppenkothen"},{"last_name":"Omand","first_name":"C.","full_name":"Omand, C."},{"last_name":"Watts","first_name":"A.
