Excluded volume effects on cold neutron star phenomenology
Observable properties of neutron stars are studied within a hadronic equation of state derived from the quark level. The effect of short-range repulsion is incorporated within the excluded volume framework. It is found that one can sustain neutron stars with masses as large as 2.2 even including hyperons in β equilibrium, while producing radii and tidal deformabilities consistent with current constraints.
期刊介绍：
