Fig. 3


Slices of modeled 3D atomic hydrogen coronae around the five Kepler-11 “super-Earths” for −107 ≤ z ≤ 107 m with a heating efficiency η = 15%. Blue and red dots correspond to neutral hydrogen atoms and hydrogen ions, which include stellar wind protons, respectively. The black dot in the center represents the planet. The white empty area around the planet corresponds to the XUV heated, hydrodynamically expanding thermosphere up to the height R0, where Kn = 0.1.
