2025-03-25 Constraint on the symmetry energy at high densities from neutron star observations using relativistic mean-field models doi:10.57760/sciencedb.j00186.00663 en In this paper, we constrain the symmetry energy at high densities in nuclear matter using recent observations of neutron stars based on the calculations of relativistic mean-field (RMF) models. Using the observations of the neutron stars, we obtain the constraint on the symmetry energy at high densities, S(2ρ0) = 40.54±12.47MeV, and S(3ρ0) = 44.12±29.38MeV.
