Abstract

In the present paper we obtain an anisotropic analogue of Durgapal-Fuloria (1985) perfect fluid solution. The methodology consists of contraction of anisotropic factor Δ\Delta by the help of both metric potentials eνe^{\nu} and eλe^{\lambda}. Here we consider eλe^{\lambda} same as Durgapal-Fuloria (1985) whereas eνe^{\nu} is that given by Lake (2003). The field equations are solved by the change of dependent variable method. The solutions set mathematically thus obtained are compared with the physical properties of some of the compact stars, strange star as well as white dwarf. It is observed that all the expected physical features are available related to stellar fluid distribution which clearly indicate validity of the model.
