Expanding Solutions to Free Boundary 3D Spherically Symmetric Compressible Navier-Stokes-Poisson Equations near the Lane-Emden Stars

Han Cao

We consider the gravitational Navier-Stokes-Poisson equations with the equation of state $P(\ddot{I})=K\ddot{I}{}^3$, where ${\hat{I}}^3\in (\frac{6}{5},\frac{4}{3}]$, which models the viscous polytropic…
