Neutron star properties with in-medium vector mesons
F. Weber, Gy. Wolf, T. Maruyama, S. Chiba
Abstract
We explore the impact of in-medium modification of the properties of vector mesons on the nuclear equation of state and neutron star properties. It is found that in-medium modifications stiffen the nuclear equation of state considerably. If this feature has its correspondence in the full treatment of dense hadronic matter, then very little room is left for the existence of exotic phases like quark matter or boson condensates in the centers of neutron stars of canonical mass.
