标题： Gravitational waves from inspiral into massive black holes

摘要： 基于空间的引力波干涉仪，如LISA，将对质量范围约为10^5个太阳质量到（几个）10^7个太阳质量的黑洞吸入恒星级致密天体的旋近过程敏感。 在旋近的最后一年，致密天体会在几个施瓦茨希尔德半径到最稳定轨道之间绕行数十万次。 这些轨道发出的引力波探测黑洞时空的强场区域，并可能实现对黑洞特性的高精度测试和测量。 测量这些波需要对波的特性有良好的理论理解，而这又需要对强场辐射反应以及可能影响波形生成的黑洞天体物理环境的特性有良好的理解。 在本次会议记录中，我回顾了宇宙中此类旋近发生的速率估计，并讨论了目前正在进行的工作以及为了计算旋近波形还需要做哪些工作。 显示英文摘要

摘要： Space-based gravitational-wave interferometers such as LISA will be sensitive to the inspiral of stellar mass compact objects into black holes with masses in the range of roughly 10^5 solar masses to (a few) 10^7 solar masses. During the last year of inspiral, the compact body spends several hundred thousand orbits spiraling from several Schwarzschild radii to the last stable orbit. The gravitational waves emitted from these orbits probe the strong-field region of the black hole spacetime and can make possible high precision tests and measurements of the black hole's properties. Measuring such waves will require a good theoretical understanding of the waves' properties, which in turn requires a good understanding of strong-field radiation reaction and of properties of the black hole's astrophysical environment which could complicate waveform generation. In these proceedings, I review estimates of the rate at which such inspirals occur in the universe, and discuss what is being done and what must be done further in order to calculate the inspiral waveform.
