Non-adiabatic gravitational collapse with anisotropic core. (English) Zbl 1200.83091
Summary: The non-adiabatic gravitational collapse of a spherical distribution of matter accompanied by radial heat flux is studied on the background of a pseudo-spheroidal space-time. The spherical distribution is divided into two regions: a core consisting of the anisotropic pressure distribution and an envelope consisting of the isotropic pressure distribution. Various aspects of the collapse are studied using both analytic and numerical methods.
