We investigate the equations of state for pure neutron matter and strange
hadronic matter in β-equilibrium, including Λ, Σ and Ξ
hyperons. The masses and radii of pure neutron stars and strange hadronic stars
are obtained. For a pure neutron star, the maximum mass is about 1.8Msun, while for a strange hadronic star, the maximum mass is
around 1.45Msun. The typical radii of pure neutron stars and
strange hadronic stars are about 11.0-12.3 km and 10.7-11.7 km, respectively.Comment: 18 pages, 7 figure
