This tool identifies all CV subtypes, including magnetic and low-accretion rate systems, in contrast to most previous surveys. We find 23 CVs, 3 of which are AM CVns, out to 150 pc in the Western Galactic Hemisphere. Our 150 pc sample is spectroscopically verified and complete down to LX = 1.3 × 1029 erg s−1 in the 0.2–2.3 keV band, and we also present CV candidates out to 300 pc and 1000 pc. We discovered two previously unknown systems in our 150 pc sample: the third nearest AM CVn and a magnetic period bouncer. We find the mean LX of CVs to be 〈LX〉 ≈ 4.6 × 1030 erg s−1, in contrast to previous surveys which yielded 〈LX〉 ∼ 1031−1032 erg s−1. We construct X-ray luminosity functions that, for the first time, flatten out at LX ∼ 1030 erg s−1. We infer average number, mass, and luminosity densities of ρN,CV = (3.7 ± 0.7) × 10−6pc−3, (math formular), and (math formular), respectively, in the solar neighborhood. Our uniform selection method also allows us to place meaningful estimates on the space density of AM CVns, ρN,AM CVn = (5.5 ± 3.7) × 10−7 pc−3. Magnetic CVs and period bouncers make up 35% and 25% of our sample, respectively. This work, through a novel discovery technique, shows that the observed number densities of CVs and AM CVns, as well as the fraction of period bouncers, are still in tension with population synthesis estimates.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by/3.0/","publication_status":"published","date_created":"2025-01-19T23:01:51Z","external_id":{"arxiv":["2408.16053"],"isi":["001393204700001"]},"department":[{"_id":"IlCa"}],"language":[{"iso":"eng"}],"status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)","legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","short":"CC BY (3.0)"},"issue":"1","day":"01","publisher":"IOP Publishing","type":"journal_article","date_published":"2025-01-01T00:00:00Z","has_accepted_license":"1","date_updated":"2025-02-27T12:46:32Z","year":"2025","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"18851","month":"01","title":"Cataclysmic variables and AM CVn binaries in SRG/eROSITA + Gaia: Volume limited samples, X-ray luminosity functions, and space densities","article_processing_charge":"No","citation":{"apa":"Rodriguez, A.

Over the past several decades, time-series photometry of CSPNe has yielded significant results including, but not limited to, discoveries of nearly 100 binary systems, insights into pulsations and winds in young white dwarfs, and studies of stars undergoing very late thermal pulses. We have undertaken a systematic study of optical photometric variability of cataloged CSPNe, using the light curves from the Zwicky Transient Facility (ZTF). By applying appropriate variability metrics, we arrive at a list of 94 highly variable CSPN candidates. Based on the timescales of the light-curve activity, we classify the variables broadly into short- and long-timescale variables. In this first paper in this series, we focus on the former, which is the majority class comprising 83 objects. We report periods for six sources for the first time, and recover several known periodic variables. Among the aperiodic sources, most exhibit a jitter around a median flux with a stable amplitude, and a few show outbursts. We draw attention to WeSb 1, which shows a different kind of variability: prominent deep and aperiodic dips, resembling transits from a dust/debris disk. We find strong evidence for a binary nature of WeSb 1 (possibly an F-type subgiant companion). The compactness of the emission lines and inferred high electron densities make WeSb 1 a candidate for either an EGB 6-type planetary nucleus, or a symbiotic system inside an evolved planetary nebula, both of which are rare objects. To demonstrate further promise with ZTF, we report three additional newly identified periodic sources that do not appear in the list of highly variable sources. Finally, we also introduce a two-dimensional metric space defined by the von Neumann statistics and Pearson Skew and demonstrate its effectiveness in identifying unique variables of astrophysical interest, like WeSb 1.","lang":"eng"}],"article_number":"024201","publication_status":"published","language":[{"iso":"eng"}],"external_id":{"arxiv":["2410.03589"],"isi":["001416903300001"]},"department":[{"_id":"IlCa"}],"date_created":"2025-02-16T23:02:33Z"},{"_id":"19439","title":"A link between White Dwarf pulsars and polars: Multiwavelength observations of the 9.36-minute period variable Gaia22ayj","month":"02","article_processing_charge":"Yes (in subscription journal)","citation":{"chicago":"Rodriguez, Antonio C., Kareem El-Badry, Pasi Hakala, Pablo Rodríguez-Gil, Tong Bao, Ilkham Galiullin, Jacob A.

However, the origin and evolution of WD magnetism remain under debate. Two WD pulsars, AR Sco and J191213.72–441045.1 (J1912), have been found, which are non-accreting binaries hosting rapidly spinning (1.97 minutes and 5.30 minutes, respectively) magnetic WDs. The WD in AR Sco is slowing down on a (math formular) yr timescale. It is believed they will eventually become polars, accreting systems in which a magnetic WD (B  ≈ 10−240 MG) accretes from a Roche lobe-filling donor spinning in sync with the orbit (≳78 minutes). Here, we present multiwavelength data and analysis of Gaia22ayj, which outbursted in 2022 March. We find that Gaia22ayj is a magnetic accreting WD that is rapidly spinning down (math formular\r\n yr) like WD pulsars, but shows clear evidence of accretion, like polars. Strong linear polarization (40%) is detected in Gaia22ayj; such high levels have only been seen in the WD pulsar AR Sco and demonstrate the WD is magnetic. High speed photometry reveals a 9.36 minutes period accompanying a high amplitude (∼2 mag) modulation. We associate this with a WD spin or spin–orbit beat period, not an orbital period as was previously suggested. Fast (60 s) optical spectroscopy reveals a broad \"hump,\" reminiscent of cyclotron emission in polars, between 4000 and 8000 Å. We find an X-ray luminosity of (math formular) in the 0.3–8 keV energy range, while two very large array radio campaigns resulted in a non-detection with a Fr < 15.8 μJy 3σ upper limit. The shared properties of both WD pulsars and polars suggest that Gaia22ayj is a missing link between the two classes of magnetic WD binaries.","lang":"eng"}],"article_number":"024202","publication_status":"published","external_id":{"arxiv":["2501.01490"],"isi":["001427877700001"]},"department":[{"_id":"IlCa"}],"date_created":"2025-03-23T23:01:26Z","language":[{"iso":"eng"}],"file":[{"checksum":"42d5aa504479c3fdf2a10165a9e3319f","content_type":"application/pdf","date_updated":"2025-03-25T10:01:24Z","date_created":"2025-03-25T10:01:24Z","file_id":"19455","creator":"dernst","file_name":"2025_PubAstronomSocPacific_Rodriguez.pdf","file_size":3291933,"relation":"main_file","access_level":"open_access","success":1}],"acknowledgement":"We wish to dedicate this work to the memory of our colleague and friend Tom Marsh.

We carried out a spectroscopic survey of 14 eclipsing systems (\"HW Vir binaries\") with orbital periods of 3.8 < Porb < 12 hr, resulting in a well-understood selection function and a near-complete sample of HW Vir binaries with G < 16. We constrain companion masses from the radial velocity curves of the sdB stars. The companion mass distribution peaks at MMS ≈ 0.15 M⊙ and drops off at MMS > 0.2 M⊙, with only two systems hosting companions above the fully convective limit. There is no correlation between Porb and MMS within the sample. A similar drop-off in the companion mass distribution of white dwarf (WD) + MS PCEBs has been attributed to disrupted magnetic braking (MB) below the fully convective limit. We compare the sdB companion mass distribution to predictions of binary evolution simulations with a range of MB laws. Because sdBs have short lifetimes compared to WDs, explaining the lack of higher-mass MS companions to sdBs with disrupted MB requires MB to be boosted by a factor of 20–100 relative to MB laws inferred from the rotation evolution of single stars. We speculate that such boosting may be a result of irradiation-driven enhancement of the MS stars' winds. An alternative possibility is that common envelope evolution favors low-mass companions in short-period orbits, but the existence of massive WD companions to sdBs with similar periods disfavors this scenario."}],"article_number":"124201","quality_controlled":"1","volume":136,"isi":1,"intvolume":"       136","file_date_updated":"2025-01-02T09:34:25Z","publication":"Publications of the Astronomical Society of the Pacific","author":[{"first_name":"Lisa","full_name":"Blomberg, Lisa","last_name":"Blomberg"},{"first_name":"Kareem","full_name":"El-Badry, Kareem","last_name":"El-Badry"},{"first_name":"Katelyn","full_name":"Breivik, Katelyn","last_name":"Breivik"},{"id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria","full_name":"Caiazzo, Ilaria","last_name":"Caiazzo","orcid":"0000-0002-4770-5388"},{"last_name":"Nagarajan","full_name":"Nagarajan, Pranav","first_name":"Pranav"},{"first_name":"Antonio","full_name":"Rodriguez, Antonio","last_name":"Rodriguez"},{"first_name":"Jan","full_name":"Van Roestel, Jan","last_name":"Van Roestel"},{"full_name":"Vanderbosch, Zachary P.","last_name":"Vanderbosch","first_name":"Zachary P."},{"first_name":"Natsuko","full_name":"Yamaguchi, Natsuko","last_name":"Yamaguchi"}],"scopus_import":"1","publication_identifier":{"issn":["0004-6280"]},"oa":1,"file":[{"access_level":"open_access","relation":"main_file","success":1,"date_updated":"2025-01-02T09:34:25Z","content_type":"application/pdf","checksum":"56fe719e26bc0c2a99ac5322791107e5","file_size":7539133,"creator":"dernst","file_name":"2024_PASP_Blomberg.pdf","date_created":"2025-01-02T09:34:25Z","file_id":"18719"}],"acknowledgement":"We thank the referee for their constructive comments.
