摘要

This paper is devoted to the study of the initial-boundary value problem for a multi-dimensional compressible Navier-Stokes-Poisson coupled system that describes the motion of a viscous gas with radiation, in the domain exterior to a ball of Rd. By means of nonlinear energy method, we show the global-in-time existence and asymptotic stability of the spherically and cylindrically symmetric solutions for large initial data, provided that the adiabatic exponent gamma is sufficiently close to 1.
