Fig. 1

Reconstructed stellar flux sorted from top to bottom according to the irradiation level at the planetary distance. HD 209458 b is plotted separately at the bottom, because we also show the radiation that is transmitted through the simulated thermosphere (shaded region). The shape of the SEDs is similar, but the XUV irradiation strength drops by more than two orders of magnitude from CoRoT-2 to GJ 436.
