Effect of electric charge on anisotropic compact stars in conformally symmetric spacetime

Abstract

We obtain a new class of interior solutions for charged anisotropic stars which admits non-static conformal motion. The Einstein–Maxwell field equations are solved by taking a physically reasonable choice for the grr metric co-efficient and a suitable expression for charge density. From the analysis we have shown that there is a central singularity on space–time by calculating Kretschmann scalar though the central density and central pressure are finite. The emphasis are given on the causality condition and the stability analysis of the model. The masses and radii of the compact stars PSR J16142230, PSR J1903 + 327 and LMC X-4 obtained from the model are well match with the observed values provided by Gangopadhyay et al (2013 Mon. Not. R.
