Well-posedness for compressible Euler equations with physical vacuum singularity
Juhi Jang, Nader Masmoudi
An important problem in the theory of compressible gas flows is to understand the singular behavior of vacuum states. The main difficulty lies in the fact that the system becomes d…

Local Well-Posedness of Dynamics of Viscous Gaseous Stars
Juhi Jang
We establish the local in time well-posedness of strong solutions to the vacuum free boundary problem of the compressible Navier-Stokes-Poisson system in the spherically symmetric…

Nonlinear Instability in Gravitational Euler-Poisson system for
Juhi Jang
The dynamics of gaseous stars can be described by the Euler-Poisson system. Inspired by Rein's stability result for , we prove the nonlinear instability of steady states f…
