Notes. Unabsorbed X-ray fluxes (FX) at Earth and luminosities (LX) are in the 0.2–10 keV band. For WASP-80 and Trappist-1 we used all available XMM observations. The stellar parallaxes and distances are from Gaia Collaboration (2021). For WASP-52, we used the count rate calculated in a 5″ region and PIMMS to estimate the flux, adopting a single APEC at 0.1 keV and solar abundances absorbed by a gas equivalent column density NH = 1020 cm−2. The data relative to V 1298 Tau are from Maggio et al. (2022) that employed the same data analysis technique we used for the other stars.
