The Pleiades open cluster was observed in multiple eROSITA all-sky survey passes, each separated by roughly six months, providing a sample of young low-mass stars with X-ray light curves. Starting from the catalogue of 850 SRG/eROSITA sources associated with Pleiades stars from Khamitov et al. (2024), we developed a flare-detection pipeline that estimates a per-survey persistent rate by...

32. The Origin of super-Eddington Flares in the high-mass X-ray binary LMC X-4

Some accreting neutron stars in massive and low-mass X-ray binaries exhibit flaring activity. The flares are accompanied by changes in spectra, pulsation profiles, and the long-term luminosity of the system. The flares themselves vary in duration and peak luminosity. Different flares have different origins; however, in many cases, the nature of the flares is unknown. In this work, we describe...
