Analytical Collapsing Solutions to Pressureless Navier-Stokes-Poisson Equations with Density-dependent Viscosity θ=1/2 in R²

Yuen, Manwai

Original · EN

We study the 2-dimensional Navier-Stokes-Poisson equations with density-dependent viscosity θ=1/2 without pressure of gaseous stars in astrophysics. The analytical solutions with collapsing in radial symmetry, are constructed in this paper.
