| 英文摘要 | In the framework of the relativistic mean field theory, we investigate (K) over bar (0) condensation along with K- condensation in neutron star matter including the baryon octet. The results show that both (K) over bar (0) and K- condensations can occur well in the core of the maximum mass stars for relatively shallow optical potentials of (K) over bar in the range of -100 MeV similar to -160 MeV. With the increasing optical potential of (K) over bar, the critical densities of (K) over bar decrease and the species of baryons appearing in neutron stars become fewer. The main role of (K) over bar (0) condensation is to make the abundances of particles become identical leading to isospin saturated symmetric matter including antikaons, nucleons and hyperons. K- condensation is chiefly responsible for the softening of the corresponding equation of state, which leads to a large reduction in the maximum masses of neutron stars. In the core of massive neutron stars, neutron star matter including rich particle species, such as antikaons, nucleons and hyperons, may exist. |
