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

Inheriting geodesic flows
TL;DR: In this article, the authors investigated the propagation equations for the expansion, vorticity and shear for perfect fluid space-times which are geodesic, assuming that space-time admits a conformal Killing vector which is inheriting so that fluid flow lines are mapped conformally.

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?]}
