A new class of viable and exact solutions of EFEs with Karmarkar conditions: an application to cold star modeling

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 J1808.4-3658. The Einstein field equations are solved by assuming that the interior of object is described class I spacetime. so-called Karmarkar condition arising from requirement integrated to reduce gravitational behaviour single generating function. By appealing physics adopt form for potential sufficiently robust accurately describe objects. Our model satisfies all requirements physically realistic structures.
