相对论平均场论在中子星性质研究中的应用

Relativistic mean-field theory applied to the study of neutron star properties

J. P. W. Diener

摘要:

核物理学可以以各种方式应用于中子星的研究。本文报道了相对论平均场近似在计算中子星内部物质状态方程中的应用。特别是导出了NL 3、PK 1和FSUGold参数集的核物质和中子星物质的物态方程。本文综述了中子星的现有文献,并利用导出的状态方程再现了饱和核物质的性质以及静态球对称中子星的质量-半径关系。结果进行了比较,发表的饱和核物质的属性值和现有的观测数据的质量半径关系的中子星。

英文摘要:

Nuclear physics can be applied in various ways to the study of neutron stars. This thesis reports on one such application, where the relativistic mean-field approximation has been employed to calculate the equations of state of matter in the neutron star interior. In particular the equations of state of nuclear and neutron star matter of the NL3, PK1 and FSUGold parameter sets were derived. A survey of available literature on neutron stars is presented and we use the derived equations of state to reproduce the properties of saturated nuclear matter as well as the mass-radius relationship of a static, spherical symmetric neutron star. Results are compared to published values of the properties of saturated nuclear matter and to available observational data of the mass-radius relationship of neutron stars.
