本文研究中子星并合中超子体黏度的效应，发现其对引力波相位影响极小，却能显著加热中子星超子核心至约5×10⁸ K，现有及下一代探测器均难探测其相位偏移效应。

本文重新研究了超子体黏度在中子星并合过程中的作用。研究发现，超子体黏度对引力波相位仅产生微小影响，引发的相位偏移约为10⁻³ rad，该偏移过小，现有引力波探测器无法探测，下一代探测器也难以将此效应与其他因素区分开。不过，分析表明超子体黏度可显著加热中子星的超子核心，使其温度升至约5×10⁸ K。
英文摘要
The paper revisits the role of hyperon bulk viscosity during neutron-star inspiral. We find that hyperon bulk viscosity exerts only a minor influence on the gravitational-wave phase, causing a phase shift of $\sim 10^{-3}\,\rm rad$. This shift is too small to be detected by existing gravitational-wave observatories, and it seems unlikely that next-generation detectors will be able to isolate this effect from other factors. However, our analysis indicates that hyperon bulk viscosity can significantly heat the hyperon core of a neutron star, raising its temperature to approximately $5 \times 10^8\,\rm K$.
