摘要：

We report an analytical expression for the locations of Lindblad resonances induced by a perturbing protoplanet, the effect of disk gravity. Inner, outer and differential torques are found to be enhanced compared to situations where velocity field for the dynamics of both the disk and the planet is assumed. Inward migration is strongly accelerated the disk gravity is only accounted for in the planet orbital motion. The addition of disk self-gravity slows down the planet drift but not enough to stop it.
