论文摘要
核反应可能会影响中子星级合并的重力波信号,但影响不确定。为了量化效果,我们比较了代表直观极端的两个数值模拟。在一个情况下,反应立即发生。在另一种情况下,它们发生在时间尺度上的速度比进化时间尺度慢得多。我们表明,尽管两个引力波信号的差异很小,但应通过第三代观测值检测到它们。为了避免从观察到的信号推断出的状态参数方程中的系统错误,我们需要在未来的模拟中准确实施核反应。
Nuclear reactions may affect gravitational-wave signals from neutron-star mergers, but the impact is uncertain. In order to quantify the effect, we compare two numerical simulations representing intuitive extremes. In one case reactions happen instantaneously. In the other case, they occur on timescales much slower than the evolutionary timescale. We show that, while the differences in the two gravitational-wave signals are small, they should be detectable by third-generation observatories. To avoid systematic errors in equation of state parameters inferred from observed signals, we need to accurately implement nuclear reactions in future simulations.
