Shell overcomes repulsive nuclear force instability
L. Satpathy,S. K. Patra +1 more
TL;DR: The infinite nuclear matter mass model and the relativistic mean field theory show a strong evidence of new neutron magic numbers 100, 150, 164; proton magic number 78 and new islands of stability around N = 100, Z 62; N = 150, Z = 78 and N = 164, Z 90 in the drip-line regions of nuclear chart as mentioned in this paper.

Direct Urca processes on nucleons in cooling neutron stars
TL;DR: In this paper, the authors used the field theoretical model to perform relativistic calculations of neutrino energy losses caused by the direct Urca processes on nucleons in the degenerate baryon matter.

Nuclear charge radii: Density functional theory meets Bayesian neural networks
TL;DR: In this paper, a Bayesian neural network (BNN) was used to generate predictions for the charge radii of thousands of nuclei throughout the nuclear chart and these predictions were refined through Bayesian learning for a neural network that is trained using residuals between theoretical predictions and the experimental data.

Non-perturbative effects in the SU(3) gluon plasma
TL;DR: In this paper, the authors consider the non-perturbation problem in quantum chromo dynamics (QCD) and derive conclusions for the SU(N) pure gauge theory from the lattice data.

Lorentz-covariant description of intermediate energy heavy-ion reactions in relativistic quantum molecular dynamics
TL;DR: In this article, the authors compared the results of the fully covariant and those of the non-covariant quantum molecular dynamics approach in describing heavy-ion reactions, and found that the difference in the results for experimental cross section (inclusive proton and pion spectra) calculated in the two approaches is very small.

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.
