The present work is mainly focused on the stellar modeling based on exact solutions of Einstein's field equation. The well behaved exact solutions are always of prime importance in relativistic scenario as they provide the basic infrastructure for modeling of stars. Due to non linear character of field equations, it is an extremely arduous task to extract new physically reasonable solutions. Using static spherically symmetric exact solutions of Einstein's field equation we have explored several models of compact stellar structures. We have generated the models based on a new form of a mass...
