摘要:

我们讨论了一些主题相关的磁盘磁层相互作用,以及如何数值模拟照亮他们。这些主题包括:(1)盘-磁层相互作用和盘闭锁问题;(2)风问题;(3)磁层流的结构、恒星表面的热点和内部盘区域;(4)三维漏斗流的光谱模拟;(5)具有复杂磁场的恒星的吸积;(6)通过三维不稳定性的吸积;(7)磁层间隙与原行星的生存。2D和3D模拟的结果进行了讨论。

英文摘要:

We discuss a number of topics relevant to disk-magnetosphere interaction and how numerical simulations illuminate them. The topics include: (1) disk-magnetosphere interaction and the problem of disk-locking; (2) the wind problem; (3) structure of the magnetospheric flow, hot spots at the star's surface, and the inner disk region; (4) modeling of spectra from 3D funnel streams; (5) accretion to a star with a complex magnetic field; (6) accretion through 3D instabilities; (7) magnetospheric gap and survival of protoplanets. Results of both 2D and 3D simulations are discussed.
