      A new model of an anisotropic compact star is obtained in our present paper by assuming the pressure anisotropy. The proposed model is singularity free. The model is obtained by considering a physically reasonable choice for the metric potential $g_{rr}$, which depends on a dimensionless parameter $n$. Theeffect of n is discussed numerically, analytically, and through plotting. We have concentrated a wide range for n ($10 \leq n \leq 1000$) for drawing the profiles of different physical parameters. The maximum allowable mass for different values of $n$ has been obtained by the $M–R$ plot. We have checked that the stability of the model is increased for a larger value of $n$. For the viability of the model, we have considered two compact stars PSR J1614-2230 and EXO 1785-248. We have shown that the expressions for the anisotropy factor andthe metric component may serve as generating functions for uncharged stellar models in the context of general theory of relativity.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
