Abstract.

The main objective of the paper is to provide a new family of solutions of embedding class one describing the interior of a spherically symmetric anisotropic stellar configuration. For \(n= 6, 8, 10\) and 12, all the physical parameters are well-behaved within the stellar interior and our model satisfies all the required conditions to be physically viable. Due to the well-behaved nature of the solution of the above n values, we develop the model of PSR J1614-2230 (Nature 467, 1081 (2010)) and discuss the behavior of the class of solutions extensively. By analyzing the adiabatic index (\(\Gamma\)) we observe that for lower values of n, i.e., \(n=6\), the star is soft and as we increase the value of n the star becomes stiff.
