Extended Data Fig. 4: The distribution of RRoche/Rs-Rxuv/Rs and the relationship between the location of sonic point and optical depths of XUV spectrum.
From: Characterization of the regimes of hydrodynamic escape from low-mass exoplanets
The dependence of the altitude distribution of the Roche radius, average absorption radius of XUV radiation and position of the sound point on the upgraded Jeans parameter. All planets orbiting G- and M-type are included. “red circle”: λ* < 3; “green triangle”: 3 < λ* < 6; “blue star”: λ* > 6.
