Top panel: comparison among the evolutions of XUV fluxes computed by following the work of Wright et al. (2011; solid yellowline), Jackson et al. (2012; solid green line), and Johnstone et al. (2021; solid red line). The horizontal black-dashed line represents the estimation of the XUV flux of Bourrier et al. (2017). Bottom panel: evolution of the planetary mass computed by considering different XUV-luminosity prescriptions. The colour code corresponds to the one described in the top panel.
