Title:
Stability of relativistic stars
Time & Venue:

Abstract:
I will discuss the stability of nonrotating relativistic stars (white drawfs, neutron stars etc.) modeled by Euler-Einstein equation. A turning point principle for the sharp stability criterion is obtained and used to explain the stability pictures with realistic equation of states. The linear instability is always true in the strong relativistic limit, in contrast to the Newtonian case modeled by Euler-Poisson system. I will also discuss the critical phenomena for gravitational collapse and its relation to the dynamics near unstable stars. This is joint work with Hadzic and Rein.
