潮汐中断事件的模拟

Simulations of Tidal Disruption Events

Giuseppe Lodato, Roseanne M. Cheng, Clement Bonnerot, Linxin Dai

摘要:

数值模拟历来发挥了重要作用,在了解流体动力学的潮汐中断过程。考虑到系统几何形状的复杂性,这个问题所带来的挑战确实激发了数值方面的大量工作。例如,光滑粒子流体动力学方法已经在潮汐破坏的背景下首次应用,并且直到今天仍然发挥着重要作用。同样,最初尝试用所谓的仿射方法模拟分裂恒星的演化在历史上非常有用。在这一章中,我们提供了一个概述的数值技术在该领域中使用的和他们的局限性,并总结了已经完成的工作,数值模拟潮汐破裂过程。

英文摘要:

Numerical simulations have historically played a major role in understanding the hydrodynamics of the tidal disruption process. Given the complexity of the geometry of the system, the challenges posed by the problem have indeed stimulated much work on the numerical side. Smoothed Particles Hydrodynamics methods, for example, have seen their very first applications in the context of tidal disruption and still play a major role to this day. Likewise, initial attempts at simulating the evolution of the disrupted star with the so-called affine method have been historically very useful. In this Chapter, we provide an overview of the numerical techniques used in the field and of their limitations, and summarize the work that has been done to simulate numerically the tidal disruption process.
