J/A+A/ TableB1:Table of exoplanet irradiation fluxes and estimated mass-loss rates (Foster+, 2021) ================================================================================ Exoplanet X-ray irradiation and evaporation rates with eROSITA G.

Schwope ================================================================================ ADC_Keywords: Stars: coronae; Stars: activity; Planet-star interactions; Planets and satellites: atmospheres; X-rays: stars Abstract: High-energy irradiation is a driver for atmospheric evaporation and mass loss in exoplanets. This work is based on data from eROSITA, the soft X-ray instrument on board the Spectrum Roentgen Gamma (SRG) mission, as well as on archival datafrom other missions. We aim to characterise the high-energy environment of known exoplanets and estimate their mass-loss rates. We use X-ray source catalogues from eROSITA, XMM-Newton, Chandra, and ROSAT to derive X-ray luminosities of exoplanet host stars in the 0.2-2 keV energy band with an underlying coronal, that is, optically thin thermal spectrum. We present a catalogue of stellar X-ray and EUV luminosities, exoplanetary X-ray and EUV irradiation fluxes, and estimated mass-loss rates for total of 287 exoplanets, 96 of which are characterised for the first time based on new eROSITA detections. We identify 14 first-time X-ray detections of transiting exoplanets that are subject to irradiation levels known to cause observable evaporation signatures in other exoplanets. This makes them suitable targets for follow-up observations. Description: This table contains an relavent parameters to characterise the high-energy environment of known exoplanets and estimate their mass-loss rates. In columns 4 and 6 values the radius and mass are given in terms of Earth mass and radius respectively. The flags in columns 5 and 7 denote planets which had no measured values for there respective mass and radius whose values were estimated according to the mass-radius relationship by Chen & Kipping 2017. Column 11 is a flag which denotes that the host star's adopted X-ray flux and all entries derived from it were adjusted for unresolved bound stellar companions. Column 12 gives provenance of the used X-ray flux is given as E/R/X/C for eROSITA, ROSAT, XMM-Newton, and Chandra, respectively.
