Saving Planetary Systems: Dead Zones and Planetary Migration [PDF]
Astrophys.J.660:1609-1623,2007, 2006 The tidal interaction between a disk and a planet leading to a planet's migration is widely believed to be the mechanism that explains the variety of orbital radii of extrasolar planets. A long-standing question is what stops the migration before planets

Dust settling and rapid planetary migration [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 Planetary migration is essential to explain the observed mass–period relation for exoplanets. Without some stopping mechanism, the tidal, resonant interaction between planets and their gaseous disc generally causes the planets to migrate inward so ...

RESONANT REMOVAL OF EXOMOONS DURING PLANETARY MIGRATION [PDF]
The Astrophysical Journal, 2015 Jupiter and Saturn play host to an impressive array of satellites, making it reasonable to suspect that similar systems of moons might exist around giant extrasolar planets.

Influence of viscosity and the adiabatic index on planetary migration [PDF]
Astronomy & Astrophysics, 2013 Context. The strength and direction of migration of low mass embedded planets depends on the disk’s thermodynamic state. It has been shown that in active disks, where the internal dissipat ion is balanced by radiative transport, migration can be dir ...

Type I Planetary Migration with MHD Turbulence [PDF]
The Astrophysical Journal, 2003 This paper examines how type I planetary migration is affected by the presence of turbulent density fluctuations in the circumstellar disk. For type I migration, the planet does not clear a gap in the disk and its secular motion is driven by torques ...

Failed Oort Clouds and Planetary Migration [PDF]
arXiv, 2000 Planet formation is accompanied by the formation of comet clouds. In systems where planets migrate on rapid timescales, the diffusive evolution of comet orbits may stall, resulting in a comet cloud intermediate between a flattened Kuiper Belt and a spherical Oort cloud.

Vertical instability and inclination excitation during planetary migration [PDF]
Celestial Mechanics and Dynamical Astronomy, Volume 119, Issue
3-4, pp. 221-235 (2014), 2014 We consider a two-planet system migrating under the influence of dissipative forces that mimic the effects of gas-driven (Type II) migration. It has been shown that, in the planar case, migration leads to resonant capture after an evolution that forces ...

ExoFrontiers, 2021 Studies of planet migration derived from disc planet interactions began before the discovery of exoplanets (see Papaloizou et al., 2007; Baruteau et al., 2014, for reviews).

Metallicity, planetary formation and migration [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 Recent observations show a clear correlation between the probability of hosting a planet and the metallicity of the parent star. Since radial velocity surveys are biased, however, towards detecting planets with short orbital periods, the probability-metallicity correlation could merely reflect a dependence of migration rates on metallicity.
