Scientific paper

We investigate the effect of disk gravity on migration of low-mass planets. We show analytically that gravitational torques exerted on the planet are stronger when the disk gravity is accounted for. Also, inward migration is accelerated in comparison with the case where the motion of both the disk and the planet is assumed to be keplerian. Preliminary hydrodynamical simulations seem to confirm these analytical predictions.
