Exoplanet X-ray irradiation and evaporation rates with eROSITA

High-energy irradiation is a driver for atmospheric evaporation and mass loss in exoplanets. This work based on data from eROSITA, the soft X-ray instrument aboard SRG (Spectrum Roentgen Gamma) mission, as well archival other missions, we aim to characterise high-energy environment of known exoplanets estimate their rates. We use source catalogues XMM-Newton, Chandra ROSAT derive luminosities exoplanet host stars 0.2-2 keV energy band with an underlying coronal, i.e. optically thin thermal spectrum. present catalogue stellar EUV luminosities, exoplanetary fluxes estimated rates total 287 exoplanets, 96 among them being characterised first time new eROSITA detections. identify 14 detections transiting that are subject levels cause observable signatures which makes suitable targets follow-up observations.
