Incompressibility of neutron-rich matter

J. Piekarewicz, M. Centelles

The saturation properties of neutron-rich matter are investigated in a relativistic mean-field formalism using two accurately calibrated models: NL3 and FSUGold. The saturation pro…

Impact of the symmetry energy on the outer crust of non-accreting neutron stars

X. Roca-Maza, J. Piekarewicz

The composition and equation of state of the outer crust of non-accreting neutron stars is computed using accurate nuclear mass tables. The main goal of the present study is to und…
