论文摘要
中微子冷却通过液固体过渡施加的非平衡条件会导致中子恒星固体地壳的疾病。疾病可减少超过中子滴的密度,$ρ_s/ρ$ $ρ_s/ρ$,$ρ_d\ y 4 \ times 10^{11} \,g/cm^3 $。对于无定形的固体地壳,$ρ_s$的抑制很小,除了地壳的最高密度区域。与晶体外壳中相干bragg散射预测的中子传导的强烈减少相反,无序的固体外壳支持足够的中子超级流体密度,以说明脉冲星的毛刺。
Nonequilibrium conditions imposed by neutrino cooling through the liquid-solid transition lead to disorder in the solid crust of neutron stars. Disorder reduces the superfluid fraction, $ρ_s/ρ$, at densities above that of neutron drip, $ρ_d \approx 4\times 10^{11}\,g/cm^3$. For an amorphous solid crust the suppression of $ρ_s$ is small, except in the highest density regions of the crust. In contrast to the strong reduction in neutron conduction predicted for coherent Bragg scattering in a crystalline crust, the disordered solid crust supports sufficient neutron superfluid density to account for pulsar glitches.
