Abstract: The SRG/eROSITA All-Sky Survey (eRASS) is a deep X-ray survey in the 0.2-10.0 keV energy band and consists of four all-sky surveys with a duration of about 0.5 yr each. The eRASS is by far the most sensitive all-sky survey in X-rays and has an unprecedented positional accuracy, spectral resolution and temporal coverage. In total it contains roughly six million X-ray sources, among them about a million stars. The first survey data was released early 2024 and the eRASS provides excellent opportunities to study the high-energy emission from various types of stellar sources, including investigations of the solar neighborhood, moving groups & associations or star-forming regions -- the stellar X-ray sky is strongly dominated by magnetically active, cool stars.
