MIGRATION RATES OF PLANETS DUE TO SCATTERING OF PLANETESIMALS
MIGRATION RATES OF PLANETS DUE TO SCATTERING OF PLANETESIMALS
Planets migrate due to the recoil they experience from scattering solid (planetesimal) bodies. To first order, the torques exerted by the interior and exterior disks cancel, analogous to the cancellation of the torques from the gravitational interaction with the gas (type I migration). Assuming the dispersion-dominated regime and power-laws characterized …
