Neutron stars and strange stars in the chiral SU(3) quark mean field model

We investigate the equations of state for pure neutron matter and strange hadronic matter in $\beta$-equilibrium, including $\mathrm{\Lambda }$, $\mathrm{\Sigma }$ and $\mathrm{\Xi }$ 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 $1.8 M_{$\mathrm{s}\mathrm{u}\mathrm{n}$}$, while for a strange hadronic star, the maximum mass is around $1.45M_{\mathrm{s}\mathrm{u}\mathrm{n}}$. 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.
