AI总结:

该研究结合 Brueckner-Hartree-Fock 与 Dyson-Schwinger 状态方程及 Gibbs 混合相构造,比较纯中子星和混合中子星的 g1 模振荡、阻尼与引力波特征及观测前景。

摘要:

我们研究纯中子星和混合中子星的非径向振荡,采用 Brueckner-Hartree-Fock 理论给出的核物质状态方程,以及 Dyson-Schwinger 夸克模型给出的夸克物质状态方程,并对混合星中的混合相进行 Gibbs 构造。文中指出了中子星与混合星在 g1 模振荡频率、阻尼时间和引力波应变上的特征差异,还讨论了观测前景。

英文摘要:

We investigate non-radial oscillations of pure and hybrid neutron stars, employing equations of state of nuclear matter from Brueckner-Hartree-Fock theory, and of quark matter from the Dyson-Schwinger quark model, performing a Gibbs construction for the mixed phase in hybrid stars. Characteristic differences between neutron-star and hybrid-star $g_1$-mode oscillation frequencies, damping times, and gravitational wave strains are pointed out. Prospects of observations are also discussed.
