论文摘要
我们对S. Postnikov等人的论文发表评论。在物理中。 Rev. D 82,024016(2010)并给出一个修改的公式,在计算中子星的潮汐爱情数量时,需要考虑到中子恒星的潮汐相位转移时发生在非零压力下。我们表明,使用原始公式时造成的错误趋向于零为$ p \ rightarrow 0 $,如果密度不连续的密度较大,我们估计最大相对误差为$ \ sim 5 \%$。
We comment on the paper of S. Postnikov et al. in Phys. Rev. D 82, 024016 (2010) and give a modified formula that needs to be taken into account when calculating the tidal Love number of neutron stars in case a first order phase-transition occurs at non-zero pressure. We show that the error made when using the original formula tends to zero as $p \rightarrow 0$ and we estimate the maximum relative error to be $\sim 5\%$ if the density discontinuity is at larger densities.
