Absorption of stellar flux in the atmosphere of a planet with Teq = 2000 K as a function of wavelength (left panel) calculated using observed solar radiation (top panel) and stellar flux without an activity-driven XUV contribution, as predicted by photospheric PHOENIX model (bottom panel). The corresponding mixing ratios are shown in the right panel (dashed line – using PHOENIX flux, solid line – using observed solar flux).
