Web28 de mai. de 2004 · We find that viscosity operating in a hypermassive star generically leads to the formation of a compact, uniformly rotating core surrounded by a low-density disk. These uniformly rotating cores are often unstable to gravitational collapse. Web23 de nov. de 2024 · Within this work, we investigate rotating stellar equilibrium models with uniform and differential rotation laws. A key tool for studying the stability of uniformly rotating models of relativistic stars is the turning-point method by Friedman, Ipser and Sorkin (Friedman, Ipser & Sorkin 1988) for equilibrium sequences.

WebWe have built quasi-equilibrium models for uniformly rotating quark stars in general relativity. The conformal flatness approximation is employed and the Compact Object … WebWe show that the neutron star minimum period of uniform rotation is determined, for causal equations of state, by the maximum value of the relativistic (compactness) parameter 2GM/Rc(2) , allowed by causality for static neutron stars, 0.7081, and by the largest measured mass of a neutron star. The relation between these three quantities, resulting …
