Abstract
Inward migration of low-mass planets and embryos of giant planets can be
stopped at the disc-cavity boundaries due to co-orbital corotation torque. We
performed the first global three-dimensional (3D) simulations of planet
migration at the disc-cavity boundary, and have shown that the boundary is a
robust trap for low-mass planets and embryos. A protoplanetary disc may have
several such trapping regions at various distances from the star, such as at
the edge of the stellar magnetosphere, the inner edge of the dead zone, the
dust-sublimation radius and the snow lines. Corotation traps located at
different distances from a star, and moving outward during the disc dispersal
phase, may possibly explain the observed homogeneous distribution of low-mass
planets with distance from their host stars.
