  journal={The Astrophysical Journal},
The presence of "hot Jupiters," Jovian-mass planets with very short orbital periods orbiting nearby main-sequence stars, has been proposed to be primarily due to the orbital migration of planets formed in orbits initially much farther from the parent star. This migration affects the evolution of inner terrestrial planets in these systems. Previous analyses have assumed that no terrestrial planets survive after migration has occurred. We present numerical simulations showing that a significant… Expand

The Influence of Massive Planet Scattering on Nascent Terrestrial Planets
In most extrasolar planetary systems, the present orbits of known giant planets admit the existence of stable terrestrial planets. Those same giant planets, however, have typically eccentric orbitsExpand
The formation and habitability of terrestrial planets in the presence of close-in giant planets
‘Hot jupiters,’ giant planets with orbits very close to their parent stars, are thought to form farther away and migrate inward via interactions with a massive gas disk. If a giant planet forms andExpand
Planetesimals in the Presence of Giant Planet Migration
We present N-body simulations illustrating how giant planet migration can significantly affect the conditions for the formation of interior terrestrial planets. A giant planet migrating through aExpand
The orbital distributions of currently observed extrasolar giant planets allow marginally stable orbits for hypothetical, terrestrial planets. In this paper, we propose that many of these systems mayExpand
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 planetsExpand
Predictions for the correlation between giant and terrestrial extrasolar planets in dynamically evolved systems
The large eccentricities of many giant extrasolar planets may represent the endpoint of gravitational scattering in initially more crowded systems. If so, the early evolution of the giant planets isExpand

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 intoExpand
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 planetaryExpand
Terrestrial planet formation in exoplanetary systems with a giant planet on an external orbit
The Epsilon Eridani and 47 UMa extrasolar systems both have moderately massive planets orbiting relatively far away from the central star (at 3.3 and beyond 2.1 AU, respectively). This peculiarityExpand
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. Expand
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 underExpand
Migrating planets
A planet orbiting in a disk of planetesimals can experience an instability in which it migrates to smaller orbital radii, which may explain the presence of Jupiter-mass objects in small orbits around nearby stars. Expand

Dynamical habitability of known extrasolar planetary systems
Habitability is usually defined as the requirement for a terrestrial planet's atmosphere to sustain liquid water. This definition can be complemented by the dynamical requirement that other planetsExpand
Volatile-rich Earth-Mass Planets in the Habitable Zone
A small planet is not necessarily a terrestrial planet. Planets that form beyond the snow line with too little mass to seed rapid gas accretion (10 M⊕) should be rich in volatile ices like H2O andExpand

It is demonstrated that the formation of terrestrial-size planets may be insulated from problems of extrasolar giant planets, enabling much of the framework of the standard model to be salvaged for use in complex systems. Expand
