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…
Cataclysmic variables from Sloan Digital Sky Survey -- V (2020-2023) identified using machine learning
Keith Inight, Boris T. Gänsicke, Axel Schwope +16
SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of 504 cataclysmic variables (CVs) and CV candida…
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…
The SRG/eROSITA all-sky survey -- Identifying the coronal content with HamStar
S. Freund, S. Czesla, P. Predehl +6
The first eROSITA all-sky survey (eRASS1) performed on board the Spectrum-Roentgen-Gamma mission (SRG) provides more than 900,000 X-ray sources in the 0.2 - 2.3 keV band located in…
A first eROSITA view of ultracool dwarfs
B. Stelzer, A. Klutsch, M. Coffaro +2
We present the first X-ray detections of ultracool dwarfs (UCDs) from the first all-sky survey of the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) onboard the…
