Query: Nonlinear Asymptomatic Stability of Gravitational Hydrostatic
  Equilibrium for Viscous White Dwarfs with Symmetric Perturbations   We prove the nonlinear asymptotic stability of the gravitational hydrostatic
equilibrium for the general equation of state of pressure-density relation in
the framework of vacuum free boundary problem of spherically symmetric
compressible Navier-Stokes-Poisson equations in three dimensions.The results
apply to white dwarfs and polytropes with $\gamma\ge 2$, for which even the
linearized asymptotic stability results are not available in literature, to the
best of the authors' knowledge. Detailed decay rates of perturbations are
given.
