Supernova and neutron stars with relativistic equations of state
TL;DR: In this paper, the properties of supernova hot stars and neutron stars using equations of state at finite temperature with arbitrary proton-to-neutron ratios derived from the relativistic mean field theory were studied.

Effect of geometrical size of the particles in a hot and dense hadron gas
M. Mishra,C. P. Singh +1 more
TL;DR: In this article, the authors proposed a new model which incorporates the excluded volume effect in a thermodynamically consistent manner and found that the new model works even for the cases of extremely large temperatures and densities where most of other approaches fail.

Vector and axial-vector mesons in nuclear matter
TL;DR: In this paper, the spectral functions of vector and axial-vector mesons in nuclear matter were calculated using the functional renormalization group (FRG) approach, and the results showed strong modifications of the spectral function near the critical endpoints of both phase transitions, which may have relevance for electromagnetic rates in heavy-ion collisions or neutrino emissivities in neutron-star merger events.

Density-dependent van der Waals model under the GW170817 constraint
TL;DR: In this article, a density-dependent function for the attractive interaction in the original van der Waals model was proposed to correctly describe the flow constraint at the high-density regime of the symmetric nuclear matter.

Fermi-liquid properties of nuclear matter in a dirac-hartree-fock approximation
Uechi Hiroshi,Uechi Hiroshi +1 more
TL;DR: In this paper, a relativistic Dirac-Hartree-Fock (DHF) approximation is examined from the point of view of the Hugenholtz-Van Hove (HV) theorem as a check for internal consistency.

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.
