A Pedagogical Look at Jeans' Density Scale
Chu, Kwang-Hua W.
European Journal of Physics, v28 n3 p501-507 May 2007
We illustrate the derivations of Jeans' criteria for the gravitational instabilities in a static homogeneous Newtonian system for pedagogical objectives. The critical Jeans density surface is presented in terms of dimensionless sound speeds and (characteristic) length scales. (Contains 1 figure.)
