Collapse of a Relativistic Self-Gravitating Star with Radial Heat Flux : Impact of Anisotropic Stresses

Abstract EN

We develop a simple model for a self-gravitating spherically symmetric relativistic star which begins to collapse from an initially static configuration by dissipating energy in the form of radial heat flow.

We utilize the model to show how local anisotropy affects the collapse rate and thermal behavior of gravitationally evolving systems.
