NON-ADIABATIC GRAVITATIONAL COLLAPSE WITH ANISOTROPIC CORE

Abstract

The non-adiabatic gravitational collapse of a spherical distribution of matter accompanied by radial heat flux has been studied on the background of a pseudo-spheroidal space–time. The spherical distribution is divided into two regions: a core consisting of anisotropic pressure distribution and an envelope consisting of isotropic pressure distribution. Various aspects of the collapse have been studied using both analytic and numerical methods.
