摘要：
We study the multi-dimensional compressible Navier Stokes Poisson system with y-law pressure and density-dependent viscosity coefficients in the simulation of the motion of gaseous stars. The global existence of spherically symmetric weak solutions to the free boundary value problem for the Navier Stokes Poisson system for y is an element of (6/5, 4/3) is shown for arbitrarily large initial data with compact support.
