原行星盘和其中形成的行星大小的天体之间的引力相互作用导致角动量交换，导致行星迁移，并可能在盘中形成更大质量行星的间隙。在本文中，我们回顾了盘与行星相互作用的基本理论，并讨论了最近嵌入原行星盘中的行星的数值模拟结果。我们考虑低质量行星的迁移以及我们对所谓的 I 型迁移的理解的最新进展，其中包括对盘热力学的更全面的处理。我们讨论中等质量行星的失控迁移（所谓的 III 型迁移）、巨行星的迁移（II 型迁移）以及该盘中相关间隙的形成。高性能计算设施的可用性使得能够计算磁化湍流盘的全局模拟，并且我们讨论了嵌入此类盘中的低质量和高质量行星的最新结果。
The gravitational interaction between a protoplanetary disc and planetary sized bodies that form within it leads to the exchange of angular momentum, resulting in migration of the planets and possible gap formation in the disc for more massive planets. In this article, we review the basic theory of disc-planet interactions, and discuss the results of recent numerical simulations of planets embedded in protoplanetary discs. We consider the migration of low mass planets and recent developments in our understanding of so-called type I migration when a fuller treatment of the disc thermodynamics is included. We discuss the runaway migration of intermediate mass planets (so-called type III migration), and the migration of giant planets (type II migration) and the associated gap formation in this disc. The availability of high performance computing facilities has enabled global simulations of magnetised, turbulent discs to be computed, and we discuss recent results for both low and high mass planets embedded in such discs.
