Abstract

A new strange star model based on Durgapal IV metric (Durgapal in J. Phys. A 15:2637, 1982) is presented here. Here we have applied a specific method to study the inner physical properties of the compact objects 4U 1702-429, 2A 1822-371, PSR J1756-2251, PSR J1802-2124 and PSR J1713+0747. The main objective of our study is to determine central density (\(\rho _{0}\)), surface density (\(\rho _{b}\)), central pressure (\(p_{0}\)), surface redshift (\(Z_{s}\)), compactness and radius. Further we perform different tests to study the stability of our model and finally we are able to give an equation based on pressure and density i.e. probable equation of state (EoS) which has an important significances in the field of Astrophysics.

Keywords
