Query: Central Density Dependent Anisotropic Compact Stars   Stars can be treated as self-gravitating fluid. In this connection, we
propose a model for an anisotropic star under the relativistic framework of
Krori-Barua (1975) spacetime. It is shown that the solutions are regular and
singularity free. The uniqueness of the model is that interior physical
properties of the star solely depend on the central density of the matter
distribution.
