Progress in constraining nuclear symmetry energy using neutron star observables since GW170817

BA Li, BJ Cai, WJ Xie, NB Zhang - Universe, 2021 - mdpi.com
The density dependence of nuclear symmetry energy is among the most uncertain parts of
the Equation of State (EOS) of dense neutron-rich nuclear matter. It is currently poorly known …
