Re: Is perturbation related to Jeans Escape Jeans escape/ Why do we care about hydrogen escape • Most H comes initially from H. 2. The Jean's escape velocity can be calculated by integrating. Using this and Jeans' escape rate, a permissible range for hydrogen escaping since the velocity distribution at the critical level (one mean free path below the

Jeans escape is a process by which atoms and molecules escape a and some of these may have velocities in excess of the escape velocity. A more accurate description of escape than a straight comparison of thermal velocity to escape velocity is the classical thermal Jeans escape. The standard view The Jeans velocity of a perturbation and the Jeans escape are two unrelated concepts named in honor of the same mathematician and
