Abstract: We propose two models for constant density relativistic perfect-fluid spheres supported by thin-shell configurations. These models are obtained from the Schwarzschild constant density star solution: the first via the collapse of the external layers of… read more here.

Abstract: In this paper, we present new physically viable interior solutions of the Einstein field equations for static and spherically symmetric anisotropic compact stars satisfying the Karmarkar condition. For presenting the exact solutions, we provide a… read more here.

DOI: 10.1142/s0218271819500032
Abstract: We present a family of relativistic fluid spheres using the Karmarkar criterion along with the Pandey–Sharma condition. Ranges of [Formula: see text] and [Formula: see text] for well-behaved solutions depend on the mass and radius… read more here.
