Abstract
In this research an anisotropic spherically symmetric core envelope model of a super dense compact star is developed. The core is represented by a linear equation of state (EOS), whereas the envelope is equipped with Van der Waals EOS. In the core and envelope of the star, all geometrical and physical factors are viable. The three regions, i.e. the core, envelope and outer space satisfy the junction conditions. The proposed model validates with the properties of the neutron stars: Vela X-1, Her X-1 and SMC X-1. It is concluded that core of the star compresses as the mass increases, justifying the dominating effect of gravity of astronomical objects with greater masses.
