Neutron skins and neutron stars in the multi-messenger era
TL;DR: A set of realistic models of the equation of state (EOS) that yield an accurate description of the properties of finite nuclei, support neutron stars of two solar masses, and provide a Lorentz covariant extrapolation to dense matter are used to confront its predictions against tidal polarizabilities extracted from the gravitational-wave data.

TL;DR: In this paper, the relativistic nuclear model was used to study the relation between the effective nucleon mass, the incompressibility, and the effective σ-meson mass in nuclear matter.

Fractional exclusion statistics applied to relativistic nuclear matter
TL;DR: In this article, the effect of the statistics of the quasiparticles in the nuclear matter at extreme conditions of density and temperature is evaluated in the relativistic mean-field model generalized to the framework of fractional exclusion statistics.

On Massive neutron cores
J. R. Oppenheimer,G. M. Volkoff +1 more
TL;DR: In this paper, the authors studied the gravitational equilibrium of masses of neutrons, using the equation of state for a cold Fermi gas, and general relativity, and showed that for masses under 1/3, there are no static equilibrium solutions.

Static Solutions of Einstein's Field Equations for Spheres of Fluid
TL;DR: In this article, a method is developed for treating Einstein's field equations, applied to static spheres of fluid, in such a manner as to provide explicit solutions in terms of known analytic functions.
Journal ArticleDOI
On Continued Gravitational Contraction
TL;DR: In this paper, the authors study the solutions of the gravitational field equations which describe the contraction of a heavy star, and give general and qualitative arguments on the behavior of the metrical tensor as the contraction progresses.
