Fig. 5.From: Variability of solar/stellar activity and magnetic field and its influence on planetary atmosphere evolutionThermospheric temperature profiles for a H-rich upper atmosphere of an Earth-like planet between the mesopause and exobase level for present day EUV (1 EUV), 2.5 EUV and 5 EUV. According to Tian et al. (2005); for an EUV flux which is 5 times that of the present Sun the exobase moves upward to about 7 Earth radii.Back to article page
