Close-in giant planets (e.g., “hot Jupiters”) are thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk. Here we simulate terrestrial planet growth during and after giant planet migration. Several-Earth-mass planets also form interior to the migrating jovian planet, analogous to recently discovered “hot Earths.” Very-water-rich, Earth-mass planets form from surviving material outside the giant planet's orbit… 
The debris disk – terrestrial planet connection
Abstract The eccentric orbits of the known extrasolar giant planets provide evidence that most planet-forming environments undergo violent dynamical instabilities. Here, we numerically simulate the
New Worlds on the Horizon: Earth-Sized Planets Close to Other Stars
Many of the planets the authors discover may be quite unlike Earth in their surface temperature and composition, but their study will nonetheless inform us about the process of planet formation and the frequency of Earth-like planets around other stars.
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
Terrestrial Planet Formation in the Presence of Migrating Super-Earths
Super-Earths with orbital periods less than 100 days are extremely abundant around Sun-like stars. It is unlikely that these planets formed at their current locations. Rather, they likely formed at

It is concluded that Earth-like planets should not expect to be typical in terms of physical and orbital properties and accretion history, and most habitable worlds are probably different, exotic worlds.
Migration & Extra-solar Terrestrial Planets: Watering the Planets
Abstract A diverse range of terrestrial planet compositions is believed to exist within known extrasolar planetary systems, ranging from those that are relatively Earth-like to those that are highly
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
Forming Close-in Earth-like Planets Via a Collision-merger Mechanism in Late-stage Planet Formation
The large number of exoplanets found to orbit their host stars in very close orbits have significantly advanced our understanding of the planetary formation process. It is now widely accepted that

Abstract Terrestrial planets form in a series of dynamical steps from the solid component of circumstellar disks. First, km-sized planetesimals form likely via a combination of sticky collisions,
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


The Search for Other Earths: Limits on the Giant Planet Orbits That Allow Habitable Terrestrial Planets to Form
Gas giant planets are far easier than terrestrial planets to detect around other stars, and they are thought to form much more quickly than terrestrial planets. Thus, in systems with giant planets,
Oligarchic and giant impact growth of terrestrial planets in the presence of gas giant planet migration
Giant planets found orbiting close to their central stars, the so-called hot Jupiters, are thought to have originally formed in the cooler outer regions of a protoplanetary disk and then to have
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
Giant Planet Formation by Gravitational Instability
The recent discoveries of extrasolar giant planets, coupled with refined models of the compositions of Jupiter and Saturn, prompt a reexamination of theories of giant planet formation. An alternative
Origin and Ubiquity of Short-Period Earth-like Planets: Evidence for the Sequential Accretion Theory of Planet Formation
The formation of gas giant planets is assumed to be preceded by the emergence of solid cores in the conventional sequential accretion paradigm. This hypothesis implies that the presence of Earth-like
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
Habitable moons around extrasolar giant planets
It is argued that rocky moons orbiting these companions could be habitable if the planet–moon system orbits the parent star within the so-called 'habitable zone'10, where life-supporting liquid water could be present.
