Nonstatic Spherically Symmetric Solutions for a Perfect Fluid in General Relativity

Nabajit Chakravarty, SB Dutta Choudhury, Aritra Banerjee

Abstract

A general method is described by which exact solutions of Einstein's field equations are obtained for a nonstatic spherically symmetric distribution of a perfect fluid. In addition to the previously known solutions which are systematically derived, a new set of exact solutions is found, and the dynamical behaviour of the corresponding models is briefly discussed.
