Description
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 iteratively excluding flare-like bins and then applies a per-bin Poisson significance test. We validated the pipeline with simulations to quantify the false-detection rate under null variability and the recovery efficiency under injected flares, and used the simulation-derived efficiency to correct the observed flare distributions. I will present the resulting flare catalogue, the population-level trends and the next analysis steps, including an extension to a wider candidate-member sample.
