Opis

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 function. The charged stellar models have been also constructed in the work based on new solutions of Einstein-Maxwell's field equations. We have presented models of immense gravity objects via embedded class one condition. The imposition of embedding class one symmetry renders the problem more easy and mathematical feasible. In the present exposition we have also considered the non static models or the collapsing fluid spheres with the emission of heat flux. The modeling of compact stars assists us in knowing the interior composition and other features of these relativistic configurations.
