Cataclysmic variables from SRG/eROSITA: new systems from eRASS1
A. D. Schwope, J. Brink, D. A. H. Buckley +12
(abridged) Aims. We aim to generate large samples of CVs selected from the SRG/eROSITA surveys to address fundamental questions about binary evolution, the role of magnetic fields…
SRG/eROSITA X-ray selected cataclysmic variable candidates observed in SDSS-V DR20
J. Brink, A. D. Schwope, K. G. Pradeep +35
We report on the spectroscopic observations obtained during SDSS-V DR20 of accreting compact binaries (ACB), specifically the cataclysmic variables (CVs), that were identified as l…
A first systematic characterization of cataclysmic variables in SRG/eROSITA surveys
Axel Schwope, Kira Knauff, Jan Kurpas +4
(abridged) We present an account of known cataclysmic variables (CVs) that were detected as X-ray sources in eROSITA X-ray surveys and have Gaia DR3 counterparts. We address standa…
An Eccentric Planet Orbiting the Polar V808 Aurigae
McKenna Leichty, Peter Garnavich, Colin Littlefield +4
We analyze 15 years of eclipse timings of the polar V808 Aur. The rapid ingress/egress of the white dwarf and bright accretion region provide timings as precise as a few tenths of…
Compact white-dwarf binaries in the combined SRG/eROSITA/SDSS eFEDS survey
A. Schwope, J. Kurpas, P. Baecke +22
Aims. Compact white-dwarf binaries are selected from spectra obtained in the early SDSS-V plate program. A dedicated set of SDSS plate observations were carried out in the eFEDS fi…
Cataclysmic Variables from Sloan Digital Sky Survey V -- the search for period bouncers continues
K. Inight, Boris T. Gänsicke, A. Schwope +25
SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of cataclysmic variables (CVs) and CV candidates…
Serendipitous discovery of the magnetic cataclysmic variable SRGE J075818-612027
Samet Ok, Georg Lamer, Axel Schwope +5
We report the discovery of SRGE J075818-612027, a deep stream-eclipsing magnetic cataclysmic variable found serendipitously in SRG/eROSITA CalPV observations of the open cluster NG…
