Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. XII. Stiffness and stability of neutron-star matter
We construct three new Hartree-Fock-Bogoliubov (HFB) mass models, labeled HFB-19, HFB-20, and HFB-21, with unconventional Skyrme forces containing ${t}_{4}$ and ${t}_{5}$ terms, i.e., density-dependent generalizations of the usual ${t}_{1}$ and ${t}_{2}$ terms, respectively. The new forces underlying these models are fitted respectively to three different realistic equations of state of …
