有限温度手征模型中的中子星

Neutron Stars in a Chiral Model with Finite Temperature

V. Dexheimer, S. Schramm, H. Stoecker

摘要:

本文用强子手征模型方法研究了中子星物质,采用了最低味SU(3)多重态的重子和介子。确定的参数,以产生一致的结果饱和核物质以及有限的核。重子共振的影响进行了讨论。确定了中子星的质量和半径等全局性质。在考虑俘获中微子、温度和熵效应的情况下,研究了原中子星的性质。

英文摘要:

Neutron star matter is investigated in a hadronic chiral model approach using the lowest flavor-SU(3) multiplets for baryons and mesons. The parameters are determined to yield consistent results for saturated nuclear matter as well as for finite nuclei. The influence of baryonic resonances is discussed. The global properties of a neutron star such as its mass and radius are determined. Proto-neutron star properties are studied by taking into account trapped neutrinos, temperature and entropy effects.
