TLDR
In this article, a model relativistic, many-body, quantum field theory composed of a baryon field, a neutral scalar meson field coupled to the scalar density ψ ψ, and a neutral vector meson fields coupled with the conserved Baryon current i Ψ γλψ is developed.About:

Hybrid Stars in the Light of GW170817
Rana Nandi,Prasanta Char +1 more
TL;DR: In this article, the effect of the tidal deformability constraint given by the binary neutron star merger event GW170817 on the equations of state (EOS) of hybrid stars was studied.

The physics of neutron stars
TL;DR: In this paper, the fundamental problems in the physics of and basic facts about neutron stars are reviewed and the observational manifestations of neutron stars, their core and envelope structure, magnetic fields, thermal evolution, and masses and radii are briefly discussed, along with the underlying microphysics.

Dilepton spectra from decays of light unflavored mesons
TL;DR: In this paper, the invariant mass spectrum of the $e^{+}e^{-}$ and $mu ^{+}\mu^{+}mu π(1020)$ pairs from decays of light unflavored mesons to final states containing along with a dilepton pair one photon, one meson, and two mesons are calculated within the framework of the effective meson theory.

Relativistic Hartree-Bogoliubov calculations with finite range pairing forces
TL;DR: In this article, a relativistic extension of Hartree-Bogoliubov theory on the basis of mean field theory is proposed, where pairing correlations are taken into account by an effective interaction of finite range adjusted by Gogny and his group.
Variation of hadron masses in finite nuclei
TL;DR: In this paper, the quark-meson coupling model was extended to investigate the change of hadron properties in finite nuclei, and a simple scaling relation for the changes of the hadron masses was found, which can be described in terms of the number of nonstrange quarks in a hadron and the value of the scalar mean field in a nucleus.

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.

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.
