论文摘要
嵌入式巨大身体与其形成的原星盘相互作用的行星盘相互作用可以在重塑行星的磁盘和轨道方面发挥重要作用。螺旋密度波被行星发射到磁盘中,如果它们足够强大,可以导致缝隙的形成。目前的仪器都可以观察到这两种效果。磁盘中引起的扰动的后反应,无论是波浪状还是非波动,都是行星轨道元素的变化。轨道迁移的效率是行星形成理论中的长期问题。我们讨论了不同行星质量和磁盘参数的行星磁盘相互作用的最新进展,尤其是湍流的水平,以及建模嵌入行星的观察性特征的进展。
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.
