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 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 () we observe that for lower values of n, i.e., , the star is soft and as we increase the value of n the star becomes stiff.
