【 摘 要 】

Einstein field equations for static anisotropic spheres are solved and exact interior solutions obtained. This paper extends earlier treatments to include anisotropic models which accommodate a wider variety of physically viable energy densities. Two classes of solutions are possible. The first class contains the limiting case 𝜇 ∝ 𝑟-2 for the energy density which arises in many astrophysical applications. In the second class the singularity at the centre of the star is not present in the energy density
