Abstract

In this article, an exact solution of Einstein's field equations for spherically symmetric anisotropic matter distributions in isotropic coordinates is obtained. For this, the solution has been obtained by using a generalized physically significant metric potential B(r) and a specific choice of the anisotropy. This new class of generalized solutions is singularity-free, which can be used to describe relativistic compact stars.
