行星-盘相互作用

Planet-Disk Interactions

摘要:

行星盘相互作用,即嵌入的大质量天体与其形成的原行星盘之间的引力相互作用,可以在重塑行星盘和行星轨道方面发挥重要作用。螺旋密度波由行星发射到圆盘中,如果它们足够强大,可以导致间隙的形成。这两种影响都可以用现有的工具观察到。在圆盘中引起的扰动的反作用,包括波动和非波动,是行星轨道要素的变化。轨道迁移的效率是行星形成理论中一个长期存在的问题。我们讨论了不同行星质量和盘参数(特别是湍流水平)的行星与盘相互作用的最新进展,以及嵌入行星观测特征建模的进展。

英文摘要:

Planet-disk interactions, where an embedded massive body interacts gravitationally with the protoplanetary disk it was formed in, can play an important role in reshaping both the disk and the orbit of the planet. Spiral density waves are launched into the disk by the planet, which, if they are strong enough, can lead to the formation of a gap. Both effects are observable with current instruments. The back-reaction of perturbations induced in the disk, both wave-like and non-wavelike, is a change in orbital elements of the planet. The efficiency of orbital migration is a long-standing problem in planet formation theory. We discuss recent progress in planet-disk interactions for different planet masses and disk parameters, in particular the level of turbulence, and progress in modeling observational signatures of embedded planets.
