| 英文摘要 | In the framework of relativistic mean field theory, the condensations of K(-) and (K) over bar (0) in neutron star matter including baryon octet and Delta quartet are studied. We find that in this case K(-) and (K) over bar (0) condensations can occur at relative shallow optical potential depth of (K) over bar from -80 MeV to - 160 MeV. Both K(-) and (K) over bar (0) condensations favor the appearances of Delta resonances. With (K) over bar condensations all the Delta quartet can appear well inside the maximum mass stars. The appearances of Delta resonances change the composition and distribution of particles at high densities. The populations of Delta resonances can enhance K(-) condensation .It is found that in the core of massive neutron stars, neutron star matter includes rich particle species, such as antikaons, baryon octet, and Delta quartet. In the presence of Delta resonances and (K) over bar condensation, the EOS becomes softer and results in smaller maximum mass stars. Furthermore the impact of antikaon condensations, hyperons, and Delta resonances on direct Urca process with nucleons is also discussed briefly. |
