Singularity-free solutions for anisotropic charged fluids with Chaplygin equation of state
arXiv:1007.1889 · doi:10.1103/PhysRevD.82.104055
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.
