当行星在气态原行星盘内形成和生长时，盘和行星之间的相互引力相互作用导致角动量的交换和行星的迁移。我们回顾了当前对盘-行星相互作用的理解，特别关注决定迁移速度和方向的物理过程。我们描述了嵌入原行星盘中的低质量行星的演化，并检查了林德布拉德和共转扭矩作为盘特性函数的影响。还讨论了圆盘在导致偏心率和倾角演变中的作用。我们描述了可能作为失控过程发生的中等质量行星的快速迁移，并研究了由大质量行星盘的粘性演化驱动的间隙形成和较慢迁移的转变。详细讨论了盘自重力和磁流体动力湍流的作用和影响，作为行星质量的函数，演化也是如此......
As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum and migration of the planet. We review current understanding of disk-planet interactions, focusing in particular on physical processes that determine the speed and direction of migration. We describe the evolution of low-mass planets embedded in protoplanetary disks and examine the influence of Lindblad and corotation torques as a function of the disk properties. The role of the disk in causing the evolution of eccentricities and inclinations is also discussed. We describe the rapid migration of intermediate-mass planets that may occur as a runaway process and examine the transition to gap formation and slower migration driven by the viscous evolution of the disk for massive planets. The roles and influence of disk self-gravity and magnetohydrodynamic turbulence are discussed in detail, as a function of the planet mass, as is the evolution...
