文摘We investigate neutron star properties by constructing a chiral SU(3) spontaneous breaking Lagrangian and using relativistic mean-field approximation. The results show that condensate appears at some baryon densities, and hyperons and exist in neutron star matter at high density. In this model, neutron star's maximum mass is with corresponding radius about 8 km.
