恒星潮汐破坏率

Rates of Stellar Tidal Disruption

Nicholas C. Stone, Eugene Vasiliev, Michael Kesden, Elena M. Rossi, Hagai B. Perets, Pau Amaro-Seoane

摘要:

潮汐破裂事件很少发生在任何单个星系中。然而,在过去的十年中,时域调查已经开始积累这些耀斑的统计样本。是什么动力学过程将恒星送入超大质量黑洞?在现实的星系核中,恒星潮汐分裂的速率是多少?通过对耀斑观测样本的潮汐扰动事件率的估计,我们可以了解到关于超大质量黑洞和更广泛的天体物理学问题的什么?这些是我们在本章中要解决的问题,本章总结了目前关于恒星潮汐破裂率的理论知识,并将理论预测与当前的观测结果进行了比较。

英文摘要:

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.
