Effects of symmetry energy on the equation of state for simulations of core-collapse supernovae and neutron-star mergers

H Shen, F Ji, J Hu, K Sumiyoshi - The Astrophysical Journal, 2020 - iopscience.iop.org
We construct a new equation of state (EOS) for numerical simulations of core-collapse
supernovae and neutron-star mergers based on an extended relativistic mean-field model …

Nonparametric Model for the Equations of State of a Neutron Star from Deep Neural Network

W Zhou, J Hu, Y Zhang, H Shen - The Astrophysical Journal, 2023 - iopscience.iop.org
It is of great interest to understand the equation of state (EOS) of the neutron star, whose
core includes highly dense matter. However, there are large uncertainties in the theoretical …

microscopic structures of neutron star matter in a vast density range with nb≈ 10− 10-2 fm …

Bayesian inference of the crust–core transition density via the neutron-star radius and neutron-skin thickness data

WJ Xie, ZW Ma, JH Guo - Nuclear Science and Techniques, 2023 - Springer
In this work, we perform a Bayesian inference of the crust–core transition density ρ t of
neutron stars based on the neutron-star radius and neutron-skin thickness data using a …

Quantum nuclear pasta and nuclear symmetry energy

FJ Fattoyev, CJ Horowitz, B Schuetrumpf - Physical Review C, 2017 - APS
Complex and exotic nuclear geometries, collectively referred to as “nuclear pasta,” are
expected to appear naturally in dense nuclear matter found in the crusts of neutron stars and …

Hadron-quark mixed phase in the quark-meson coupling model

M Ju, X Wu, F Ji, J Hu, H Shen - Physical Review C, 2021 - APS
We explore the possibility of a structured hadron-quark mixed phase forming in the interior of
neutron stars. The quark-meson coupling (QMC) model, which explicitly incorporates the …

Elastic properties of phases with nonspherical nuclei in dense matter

CJ Pethick, ZW Zhang, DN Kobyakov - Physical Review C, 2020 - APS
We consider the elastic constants of phases with nonspherical nuclei, so-called pasta
phases, predicted to occur in the inner crust of a neutron star. First, we treat perfectly ordered …

Effects of nuclear symmetry energy and equation of state on neutron star properties

F Ji, J Hu, S Bao, H Shen - Physical Review C, 2019 - APS
We study the effects of nuclear symmetry energy on the mass-radius relation and tidal

Nuclear symmetry energy and hadron-quark mixed phase in neutron stars

XH Wu, H Shen - Physical Review C, 2019 - APS
We study the hadron-quark mixed phase, which may occur in the interior of neutron stars.
