Role of Durgapal-Fuloria model on isotropic spheres in Rastall gravity
摘要
This research deals with the impacts of Rastall parameter on the physical behavior of isotropic compact stars. For this purpose, the static spherically symmetric as well as perfect fluid distribution are taking into account. To examine the various aspects of some particular compact star models, the Durgapal-Fuloria metric functions are considered. The unknown parameters involved in Durgapal-Fuloria metric functions are computed via matching constraints with observed choices of masses and radii of few particular stellar objects. The viability of the endorsed functions is inspected through the graphical description of matter contents, energy constraints, equation of state factor, mass constituents, causality condition and stellar equation for certain values of Rastall parameter. It is determined that the stars under consideration manifest stable structures corresponding to Durgapal-Fuloria metric potentials in this framework. Further, it is exhibited that for Rastall factor equals to zero, the general results of theory of relativity can be achieved.
