吸积盘中的Angular momentum输运：流体动力学观点
Angular momentum transport in accretion disks: a hydrodynamical perspective
摘要：
吸积盘中角动量的径向输运是宇宙中的一个基本过程。它支配着吸积盘的动力学演化，并对从行星的形成到超大质量黑洞的生长等各种问题都有影响。虽然磁场对这一问题的重要性早已得到证明，但事实证明，在自然界中存在一个纯粹的流体动力学传输源更难以建立和量化。近年来，实验、理论和数值模拟的结合极大地提高了我们对吸积盘中流体介导的角动量输运的认识。在这里，基于这些最新的发展，我们审查的流体动力学过程，可能有助于径向输送角动量的吸积盘，并突出了许多问题，仍然有待回答。
英文摘要：
The radial transport of angular momentum in accretion disk is a fundamental process in the universe. It governs the dynamical evolution of accretion disks and has implications for various issues ranging from the formation of planets to the growth of supermassive black holes. While the importance of magnetic fields for this problem has long been demonstrated, the existence of a source of transport solely hydrodynamical in nature has proven more difficult to establish and to quantify. In recent years, a combination of results coming from experiments, theoretical work and numerical simulations has dramatically improved our understanding of hydrodynamically mediated angular momentum transport in accretion disk. Here, based on these recent developments, we review the hydrodynamical processes that might contribute to transporting angular momentum radially in accretion disks and highlight the many questions that are still to be answered.
