P. C. Vaidya,Ramesh Tikekar +1 more
TLDR
In this article, a static spherically symmetric model based on an exact solution of Einstein's equations is given which will permit densities of the order of 2 × 1014 gm cm-3, radii of a few kilometers and masses up to about four times the solar mass.Abstract:
Assuming that the physical 3-spacet = const in a superdense star is spheroidal, a static spherically symmetric model based on an exact solution of Einstein’s equations is given which will permit densities of the order of 2 × 1014 gm cm-3, radii of the order of a few kilometers and masses up to about four times the solar mass.read more

An electromagnetic extension of the Schwarzschild interior solution and the corresponding Buchdahl limit
TL;DR: In this article, a model for a charged star as a generalization of the uniform density Schwarzschild interior solution is presented. But the model is based on the Vaidya and Tikekar ansatz (Astrophys Astron 3:325, 1982).

An exact solution of einstein equations for interior field of an anisotropic fluid sphere
TL;DR: In this article, an anisotropic relativistic fluid sphere with variable density, which decreases along the radius and is maximum at the centre, is discussed, and a spherically symmetric static space-time with spheroidal physical 3-space is considered.

Maximum Mass of a Neutron Star
Clifford E. Rhoades,Remo Ruffini +1 more
TL;DR: On the basis of the theory of relativity, the principle of causality, and Le Chatelier's principle, it was shown in this article that the maximum mass of the equilibrium configuration of a neutron star cannot be larger than $3.2{M}_{[m?]}
