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

Relativistic star solutions in higher-dimensional pseudospheroidal space-time
TL;DR: In this paper, the authors obtained relativistic solutions of a class of compact stars in hydrostatic equilibrium in higher dimensions by assuming a pseudospheroidal geometry for the spacetime.

Relativistic strange stars with anisotropy
TL;DR: In this paper, the authors analyzed the effect of pressure anisotropy on the Bag parameter for a compact star described by Vaidya-Tikekar metric and determined the values of B inside and on surface of the star.

Symmetry, Singularities and Integrability in Complex Dynamics I: The Reduction Problem
TL;DR: In this article, the authors show that quadratic systems generated using Yang-Baxter equations are integrable in a sense, but display a deterioration in the possession of the Painleve property as the number of equations in each "integrable" system increases.

Relativistic solution for a class of static compact charged star in pseudo-spheroidal spacetime
TL;DR: In this paper, the relativistic solution for the theory is used to obtain models for charged compact objects; thereafter, a qualitative analysis of the physical aspects of compact objects are studied.

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?]}
