Abstract

In this work a new class of relativistic solutions for anisotropic strange star has been investigated taking into account the inner spacetime represented by Durgapal IV metric potential. We have obtained the solutions of the Einstein eld equations in exact form to construct a viable stellar model. The basic characteristics parameter relevant to model are well obeyed in the present scenario. In the present model, the maximum mass is determined by maximizing the rad ial sound velocity at the centre. We note that, for an isotropic stellar configuration, the maximum masses are found 1.911 M?, 2.123 M? and 2.335 M? respectively for radii b = 9 Km, b = 10 Km and b = 11 Km. It is observed that in  presence of anisotropy maximum mass increases. Using our model, the radii of a few recently spotted compact stars and pulsars have been predicted and we note that our theoretical predictions align well with the estimated results from observations. Moreover, all of the energy requirements and stability standards needed to de ne a stable stellar structure are achieved by the present model.
