论文摘要
在通过地面引力波观测可检测到的三种主要类型的二进制室中，黑洞中子星（BHNS）合并仍然是最难以捉摸的。尽管候选人BHN存在于高级Ligo/处女座合作的第三次观察过程中发布的触发器中，但到目前为止尚未确认检测。至于二进制中子星系，BHNS二进制文件使我们能够探索广泛的物理过程，包括状态的中子星方程，核合成，恒星进化，高能天体物理学以及宇宙的扩展。在这里，我们回顾了BHNS系统的一些主要特征：破坏和非中断二进制文件之间的区别，BHNS合并可以产生的流出类型以及可以从观察其引力波和电磁信号的信息中提取的信息。我们还强调，对于最可能的二元参数，BHNS合并似乎比二元中子星系供电电磁信号供电。最后，我们讨论了一些仍然限制我们建模和解释来自BHNS二进制的电磁信号的能力的问题。
Of the three main types of binaries detectable through ground-based gravitational wave observations, black hole-neutron star (BHNS) mergers remain the most elusive. While candidates BHNS exist in the triggers released during the third observing run of the Advanced LIGO/Virgo collaboration, no detection has been confirmed so far. As for binary neutron star systems, BHNS binaries allow us to explore a wide range of physical processes, including the neutron star equation of state, nucleosynthesis, stellar evolution, high-energy astrophysics, and the expansion of the Universe. Here, we review some of the main features of BHNS systems: the distinction between disrupting and non-disrupting binaries, the types of outflows that BHNS mergers can produce, and the information that can be extracted from the observation of their gravitational wave and electromagnetic signals. We also emphasize that for the most likely binary parameters, BHNS mergers seem less likely to power electromagnetic signals than binary neutron star systems. Finally, we discuss some of the issues that still limit our ability to model and interpret electromagnetic signals from BHNS binaries.
