Singularity-free solutions for anisotropic charged fluids with Chaplygin equation of state

General Physics 2010-12-23 v2 General Relativity and Quantum Cosmology

Abstract

We extend the Krori-Barua analysis of the static, spherically symmetric, Einstein-Maxwell field equations and consider charged fluid sources with anisotropic stresses. The inclusion of a new variable (tangential pressure) allows the use of a non-linear, Chaplygin-type equation of state with coefficients fixed by the matching conditions at the boundary of the source. Some physical features are briefly discussed.
