Contribution

It introduces a simple, static-to-collapsing star model incorporating anisotropic stresses and heat flux, analyzing their impact on collapse rate and thermal behavior.

Findings

Anisotropic stresses influence collapse rate.

Radial heat flux affects thermal evolution.

Model demonstrates the role of anisotropy in gravitational collapse.

Abstract

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 effects the collapse rate and thermal behaviour of gravitationally evolving systems.
