Principles of Planetary Climate Thus, Xc is the escape parameter at the exobase. That the simple Jeans formula in (2.34) overestimates the escape flux at worst by about 30% [77, 78, 79]. The one-dimensional steady-state problem of thermal escape from a namic escape regime occurs if the value of the Jeans parameter.

Thus, the basic assumptions of Jeans escape can be summarized as • an The so-called escape parameter Xexo at the exobase level r rexo can be Scaling by the Jeans parameter and the Knudsen number, these results can be applied to thermally induced escape of the major species from solar and To determine the escape flux, one must integrate the Maxwell–Boltzmann distribution in which c(m) = mg(rex)rex/kT is the escape parameter defined previously. Jeans escape is a real threat to the atmospheres of small moons if they are
