Description
Summary:We propose a model for relativistic compact star with anisotropy and analytically obtain exact spherically symmetric solutions which describe interior of the dense star admitting non-static conformal symmetry. Several features of the solutions, including drawbacks of the model, have been explored and discussed. For this purpose we have provided the energy conditions, TOV equation and other physical requirements and thus thoroughly have investigated stability, mass-radius relation and surface redshift of the model. It is observed that most of the features are well matched with the compact strange stars.
