Giant planets in circumstellar disks can migrate inward from their initial (formation) positions. Radial migration is caused by inward torques between the planet and the disk, by outward torques between the planet and the spinning star, and by outward torques due to Roche lobe overflow and consequent mass loss from the planet. We present self-consistent numerical considerations of the problem of migrating giant planets. Summing torques on planets for various physical parameters, we find that…

Formation of Earth-like Planets During and After Giant Planet Migration

Close-in giant planets are thought to have formed in the cold outer regions of planetary systems and migrated inward, passing through the orbital parameter space occupied by the terrestrial planets

Planetary migration

Gravitational torques between a planet and gas in the protoplanetary disk result in orbital migration of the planet, and modification of the disk surface density. Migration via this mechanism is


We present models of giant planet migration in evolving protoplanetary disks. Our disks evolve subject to viscous transport of angular momentum and photoevaporation, while planets undergo Type II

Planetary Migration: What Does It Mean for Planet Formation?

Gravitational interactions between a planet and its protoplanetary disk change the planet’s orbit, causing the planet to migrate toward or away from its star. Migration rates are poorly constrained

Outward migration of extrasolar planets to large orbital radii

Observations of structure in circumstellar debris discs provide circumstantial evidence for the presence of massive planets at large (several tens of astronomical units) orbital radii, where the

Easy Come, Easy Go: Orbital Migration and the Frequency of Giant Planet Formation

We present a statistical study of the post-formation migration of giant planets in a range of initial disk conditions. For given initial conditions we model the evolution of giant planet orbits under

On the formation of terrestrial planets in hot-Jupiter systems

Context. There are numerous extrasolar giant planets which orbit close to their central stars. These “hot-Jupiters” probably formed in the outer, cooler regions of their protoplanetary disks, and

A Reduced Efficiency of Terrestrial Planet Formation following Giant Planet Migration

Substantial orbital migration of massive planets may occur in most extrasolar planetary systems. Since migration is likely to occur after a significant fraction of the dust has been locked up into

Orbital Migration Of Giant Planets: Using Numerical Integration To Investigate Consequences For Other Bodies

A number of extrasolar planets have been detected in close orbits around nearby stars. It is probable that these planets did not form in these orbits but migrated from their formation locations


Recent discoveries of several transiting planets with clearly non-zero eccentricities and some large obliquities started changing the simple picture of close-in planets having circular and



Gravitational scattering as a possible origin for giant planets at small stellar distances

An alternative model for planetary migration that can account for two large orbital eccentricities of giant planets that are difficult to reconcile with a tidal-linkage model is described.

On the Origin of Massive Eccentric Planets

We propose a merger scenario for the newly discovered extrasolar planets around 70 Vir (Marcy & Butler) and HD 114762 (Latham, Stefanik, & Mazeh; Marcy & Butler). These planets have mass Mp sin i =

Orbital migration of the planetary companion of 51 Pegasi to its present location

THE recent discovery1 and confirmation2 of a possible planetary companion orbiting the solar-type star 51 Pegasi represent a breakthrough in the search for extrasolar planetary systems. Analysis of

Inhibition of giant-planet formation by rapid gas depletion around young stars

Observations of the molecular gas surrounding 20 stars whose ages are likely to be in this range are reported, finding that the gas dissipates rapidly; after a few million years the mass remaining is typically much less than the mass of Jupiter.

Giant Planets at Small Orbital Distances

Using Doppler spectroscopy to detect the reflex motion of the nearby star, 51 Pegasi, Mayor & Queloz (1995) claim to have discovered a giant planet in a 0.05 AU, 4.23 day orbit. They estimate its

Formation of the Giant Planets by Concurrent Accretion of Solids and Gas

New numerical simulations of the formation of the giant of the second phase. planets are presented, in which for the first time both the gas and The actual rates at which the giant planets accreted

The Search for Forming Planetary Systems

For the first few million years of its life, the Sun was a large red star surrounded by a disk of gas and dust—the primitive solar nebula—that reached out beyond the boundaries of our present

Dynamical Instabilities and the Formation of Extrasolar Planetary Systems

The existence of a dominant massive planet, Jupiter, in our solar system, although perhaps essential for long-term dynamical stability and the development of life, may not be typical of planetary

Tidal decay of close planetary orbits

The 4.2-day orbit of the newly discovered planet around 51~Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetime
