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…
Unveiling the period-bounce population of cataclysmic variables: Spectroscopic and time-domain follow-up of eROSITA-selected candidates
S. Hernández-Díaz, B. Stelzer, A. Schwope +9
During their secular evolution, cataclysmic variable stars (CVs) evolve toward shorter orbital periods () until reaching a minimum near min, after…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
XMM-Newton follow-up of two eROSITA X-ray binary candidates
A. Avakyan, A. Zainab, V. Doroshenko +6
We report on the follow-up observations with XMM-Newton of two X-ray binary candidates identified in the first eROSITA all-sky survey data (eRASS1), 1eRASS J061330.8+160440 and 1eR…
Discovery of the magnetic cataclysmic variable XMM J152737.4-205305.9 with a deep eclipse-like feature
Samet Ok, Axel Schwope, David A. H. Buckley +1
In this study, we report a discovery from XMM-Newton, which involves the identification and subsequent examination of a newly discovered polar-type cataclysmic variable named XMM J…
The more the merrier: SRG/eROSITA discovers two further galaxies showing X-ray quasi-periodic eruptions
R. Arcodia, Z. Liu, A. Merloni +20
X-ray quasi-periodic eruptions (QPEs) are a novel addition to the group of extragalactic transients. In this work, we report the discovery of two further galaxies showing QPEs, eRO…
Unveiling the white dwarf in J191213.72-441045.1 through ultraviolet observations
Ingrid Pelisoli, Snehalata Sahu, Maxim Lyutikov +7
J191213.72-441045.1 is a binary system composed of a white dwarf and an M-dwarf in a 4.03-hour orbit. It shows emission in radio, optical, and X-ray, all modulated at the white dwa…
A 5.3-minute-period pulsing white dwarf in a binary detected from radio to X-rays
Ingrid Pelisoli, T. R. Marsh, David A. H. Buckley +19
White dwarf stars are the most common stellar fossils. When in binaries, they make up the dominant form of compact object binary within the Galaxy and can offer insight into differ…
