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…

Confirmation of SRGt 062340.2-265751 as a nova-like cataclysmic variable with a possible magnetic nature

V. A. Cúneo, A. D. Schwope, J. Kurpas +5

SRGt 062340.2-265751, a cataclysmic variable identified by SRG/eROSITA thanks to its significant X-ray variability, remains poorly characterised despite the multi-wavelength follow…

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…

SRG/eROSITA No. 5: Discovery of quasi-periodic eruptions every ~3.7 days from a galaxy at z>0.1

R. Arcodia, P. Baldini, A. Merloni +17

Quasi-periodic eruptions (QPEs) are repeating soft X-ray bursts from the nuclei of galaxies, tantalizingly proposed to be extreme mass ratio inspirals. Here, we report the discover…

A close binary lens revealed by the microlensing event Gaia20bof

E. Bachelet, P. Rota, V. Bozza +24

During the last 25 years, hundreds of binary stars and planets have been discovered towards the Galactic Bulge by microlensing surveys. Thanks to a new generation of large-sky surv…

eRASSUJ060839.5-704014: A double degenerate ultra-compact binary in the direction of the LMC

C. Maitra, F. Haberl, G. Vasilopoulos +7

Context. During four all-sky surveys (eRASS1--4), eROSITA, the soft X-ray instrument aboard Spektrum-Roentgen-Gamma (SRG) detected a new supersoft X-ray source, eRASSU J060839.5-70…
