Abstract

In this paper, we present a new exact anisotropic charged version of Pant's interior solution [Astrophys. Space Sci. 331, 633 (2011)] by employing the embedding class I condition and the gravitational decoupling via minimal geometric decoupling (MGD) approach. We successfully integrate the coupled Einstein–Maxwell field equations within the MGD and generate a family of new charged anisotropic solutions describing compact stellar objects. The matching of the interior to the exterior Reissner–Nordstrom solution help fix the arbitrary constants. For a chosen parameter space we subject our model to rigorous tests in order to validate its physical viability as a realistic self-gravitating, compact object. We show that the deformation parameter σ is intrinsically connected to key features such as compactness, mass-to-radius ratio and surface redshift for compact star candidates such as Her X-1, EXO 1785-248, PSR J1614-2230 and SAX J1808.4-3658.
