Global dynamics of viscous gaseous stars in a physical vacuum
Demin Wang, Jiawen Zhang, Shengguo Zhu
The study of vacuum is important in understanding compressible flows. In particular, physical vacuum, in which the boundary moves with a nontrivial finite normal acceleration, natu…

On a Local Existence Theorem for the Evolution Equation of Viscous Gaseous Stars in a Physical Vacuum
Demin Wang, Jiawen Zhang, Shengguo Zhu
This paper focuses on the free boundary problem of the three-dimensional compressible Navier-Stokes-Poisson equations with degenerate viscosities for self-gravitating viscous gaseo…
