Equation of state for neutron stars: Hyperon mixing in SU(3) flavor symmetry

Abstract

Using various kinds of relativistic mean-field models as well as the quark-meson coupling model, we study in detail the properties of neutron stars. We find that the equation of state in SU(3) flavor symmetry can support a neutron star with mass of (1.8 2.1) M even if hyperons exist inside the core of a neutron star.
