英文摘要In the RMF approach, considering the contributions of the sigma* and phi mesons and the hyperons in the baryon octet {N, P, Lambda, Sigma(-), Sigma(0), Sigma(+), Xi(-), Xi(0)}, the properties of neutron star matter have been investigated. It is found that with the contributions of the sigma* and phi mesons, the critical baryon density of hyperon appearance decreases, the number of hyperons increases, the transition density rho(0H) of hyperon stars decreases, the equation of state turns soft, the maximum mass of neutron star decreases and the corresponding radius increases, the central density, the central energy density and the central pressure are all reduced.
