Abstract

The motion of the self-gravitational gaseous stars can be described by the Euler-Poisson equations. The main purpose of this article is concerned with the nonlinear stability of gaseous stars  in the non-isentropic case, when
4/3 < γ <2, S(x, t) is a smooth bounded function. First, we verify  that  the steady states are minimizers of the energy via concentration-compactness method; then using the variational approach we obtain the stability results of the non-isentropic flow.
