Thermospheric temperature profiles between 100 km and the corresponding exobase levels for 1 (present), 3.3, 5.3, 7, 10 and 20 times higher EUV solar fluxes than today, applied to Earth with the present time atmospheric composition (Tian et al., 2008a; Lammer et al., 2008). One can see that the thermosphere switches in a non-hydrostatic regime for T ≥ 8000 K and expands dynamically up to distances beyond 10 planetary radii.
