中子星的重子超流性和中微子发射率

Baryon superfluidity and neutrino emissivity of neutron stars

T. Takatsuka, R. Tamagaki

摘要:

对于具有超子混合核的中子星,为了保证中微子的最大质量与观测相符,引入了对所有重子都适用的三体排斥力,在状态方程下研究了中微子发射率。通过关注重子超流体临界温度的密度依赖性,这反映了重子-重子相互作用的性质,并控制中子星冷却,我们显示了什么中微子发射过程是有效的,在有和没有超子混合的区域,并评论其与中子星冷却有关的影响。

英文摘要:

For neutron stars with hyperon-mixed core, neutrino emissivity is studied under the equation of state, obtained by introducing repulsive three-body force universal for all baryons so as to assure the maximum mass compatible with the observation. By paying attention to the density-dependence of critical temperatures of baryon superfluids, which reflect the nature of baryon-baryon interaction and control neutron star cooling, we show what neutrino emission processes are efficient in the regions with and without hyperon mixing and remark its implications related to neutron star cooling.
