, 2008 Gravitational torques between a planet and gas in the protoplanetary disk result in orbital migration of the planet, and are likely to play an important role in the formation and early evolution of planetary systems. For masses comparable to those of observed giant extrasolar planets, the interaction with the disk is strong enough to form a gap ...

The effect of planetary migration on the corotation resonance [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 The migration of a planet through a gaseous disc causes the locations of their resonant interactions to drift and can alter the torques exerted between the planet and the disc. We analyse the time-dependent dynamics of a non-coorbital corotation resonance under these circumstances.

How planetary growth outperforms migration [PDF]
Astronomy & Astrophysics, 2019 Planetary migration is a major challenge for planet-formation theories. The speed of type-I migration is proportional to the mass of a protoplanet, while the final decade of growth of a pebble-accreting planetary core takes place at a rate that scales with the mass to the two-thirds power. This results in planetary growth tracks (i.e., the evolution of

TOI-1333Ab is on a well-aligned orbit
Astronomy & AstrophysicsContext. Spin-orbit obliquity measurements of hot-Jupiter systems constrain giant planet migration and tidal evolution. In binary systems, combining stellar obliquities with the orbit-orbit angle (γ) between the planetary and stellar companion orbits ...

Planetary migration in resonance : the question of the eccentricities [PDF]
EAS Publications Series, 2010 The formation of resonant planets pairs in exoplanetary systems involves planetary migration inside the protoplanetary disc: an inwards migrating outer planet captures in Mean Motion Resonance an inner planet. During the migration of the resonant pair of planets, the eccentricities are expected to rise excessively, if no damping mechanism is applied on

The Astrophysical JournalMigration typically occurs during the formation of planets and is closely linked to the planetary formation process. In classical theories of nonaccreting planetary migration, both type I and type II migration typically result in inward migration, which ...
