  • Within the RMF approach, considering the contribution of σ*,φ mesons and baryon octet {n,p,Λ,Σ－,Σ0,Σ+,Ξ－,Ξ0}, some properties of neutron star matter have been investigated in the temperature region between 5—15MeV.

At T=5MeV and 10MeV and for Σ0,Ξ0,Σ+, the σ*,φ mesons make critical baryon density greatly decrease; but at T=15MeV, 20MeV, and 25MeV, the effect is not obvious.

Abstract: Within the RMF approach, considering the contribution of σ*,φ mesons and baryon octet {n,p,Λ,Σ－,Σ0,Σ+,Ξ－,Ξ0}, some properties of neutron star matter have been investigated in the temperature region between 5—15MeV. It is found that when the contributions of σ*,φ mesons are included, (1) the critical baryon density decreases (but for the Λ hyperon, the effect is not obvious), but the number of hyperons increases; (2) the equation of state becomes soft at higher energy density; (3) the maximum mass decreases while the corresponding radius increases; (4) the central density, the central energy density, and the central pressure all become smaller. At T=5MeV and 10MeV and for Σ0,Ξ0,Σ+, the σ*,φ mesons make critical baryon density greatly decrease; but at T=15MeV, 20MeV, and 25MeV, the effect is not obvious. However, for Λ,Σ－,Ξ－ hyperons, at all the above temperatures, the effect is not obvious.
