【 摘 要 】

A model for the non-adiabatic collapse of a spherically symmetric anisotropic distribution of matter accompanied with radial heat flux has been presented. This is an inhomogeneous generalization of the model, describing collapse of a homogeneous distribution of isotropic fluid and, therefore, provides a mechanism to investigate the impacts of inhomogeneity and anisotropic stresses on the collapse of a radiating star.
