Tidal disruption events occur rarely in any individual galaxy. Over the last decade, however, time-domain surveys have begun to accumulate statistical samples of these flares. What dynamical processes are responsible for feeding stars to supermassive black holes? At what rate are stars tidally disrupted in realistic galactic nuclei? What may we learn about supermassive black holes and broader astrophysical questions by estimating tidal disruption event rates from observational samples of flares? These are the questions we aim to address in this Chapter, which summarizes current theoretical knowledge about rates of stellar tidal disruption, and compares theoretical predictions to the current state of observations.

恒星潮汐中断率

潮汐破坏事件在任何单个星系中都很少发生。然而，在过去十年中，时域调查已经开始积累这些耀斑的统计样本。什么动力过程负责将恒星馈送到超大质量黑洞？在现实的星系核中，恒星被潮汐破坏的速度是多少？通过估计耀斑观测样本的潮汐破坏事件率，我们可以了解超大质量黑洞和更广泛的天体物理学问题吗？这些是我们在本章中旨在解决的问题，本章总结了当前关于恒星潮汐破坏率的理论知识，并将理论预测与当前的观测状态进行了比较。
