Comments on ‘Type II migration strikes back – an old paradigm for planet migration in discs’ by Scardoni et al.
ABSTRACT In the conventional view of type II migration, a giant planet migrates inward in the viscous velocity of the accretion disc in the so-called disc-dominate case. Recent hydrodynamic simulations, however, showed that planets migrate with velocities much faster than the viscous one in massive discs. Such fast migration cannot …
