摘      要：In this work we present a theoretical framework within Einstein’s classical general relativity which models stellar compact objects such as PSR J1614-2230 and SAX *** Einstein field equations are solved by assuming that the interior of the compact object is described by a class I *** so-called Karmarkar condition arising from this requirement is integrated to reduce the gravitational behaviour to a single generating *** appealing to physics we adopt a form for the gravitational potential which is sufficiently robust to accurately describe compact *** model satisfies all the requirements for physically realistic stellar structures.
