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 $P(\rho )=K{\rho }^{\gamma }$, where $\gamma \in (\frac{6}{5},\frac{4}{3}]$, which models the viscous polytropic gas…
