SRG/eROSITA X-ray selected cataclysmic variable candidates observed in SDSS-V DR20

J. Brink, A. D. Schwope, K. G. Pradeep +35

The paper presents spectroscopic observations from SDSS‑V of cataclysmic variable candidates identified via X‑ray detections in the SRG/eROSITA eRASS1 and eRASS3 surveys, assemblin…

The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy

W. Yu, A. F. Pala, T. Kupfer +33

AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…

Unsupervised learning for variability detection with Gaia DR3 photometry. The main sequence-white dwarf valley

P. Ranaivomanana, C. Johnston, G. Iorio +4

The unprecedented volume and quality of data from space- and ground-based telescopes present an opportunity for machine learning to identify new classes of variable stars and pecul…

Variability in hot sub-luminous stars and binaries: Machine-learning analysis of Gaia DR3 multi-epoch photometry

P. Ranaivomanana, M. Uzundag, C. Johnston +3

Hot sub-luminous stars represent a population of stripped and evolved red giants that is located on the extreme horizontal branch. Since they exhibit a wide range of variability du…
