We examine the effect of a rapidly migrating protoplanet on a ring of planetesimals. The eccentricities of the planetesimals are usually increased bye ∈ (0.01, 0.1), with the exact increase being proportional to the mass of the protoplanet, and inversely proportional to its migration rate. The eccentricity distribution is also substantially changed from a Rayleigh distribution. We discuss the possible implications for further planet formation, and suggest that the rapid passage of a protoplanet… Expand

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
Planetary migration poses a serious challenge to theories of planet formation. In gaseous and planetesimal disks, migration can remove planets as quickly as they form. To explore migration in aExpand
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
Collisional evolution of eccentric planetesimal swarms
Models for the steady state collisional evolution of low eccentricity planetesimal belts identify debris disks with hot dust at 1AU, likeCorvi and HD69830, as anomalous since collisional processingExpand

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,Expand
Effects of Dynamical Evolution of Giant Planets on the Delivery of Atmophile Elements During Terrestrial Planet Formation
Recent observations started revealing the compositions of protostellar discs and planets beyond the Solar System. In this paper, we explore how the compositions of terrestrial planets are affected byExpand
Exotic Earths: Forming Habitable Worlds with Giant Planet Migration
This simulation of terrestrial planet growth during and after giant planet migration is applied to close-in giant planets thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk. Expand
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
Close-Orbiting Exoplanets: Formation, Migration Mechanisms and Properties
The discovery of a signal from a putative extra-solar planet around the nearby Sun-like star 51 Peg by Mayor & Queloz and the rapid confirmation by Marcy & Butler was the main starting point for theExpand
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


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
Disk tides and accretion runaway
It is suggested that tidal interaction of an accreting planetary embryo with the gaseous preplanetary disk may provide a mechanism to breach the so-called runaway limit during the formation of theExpand
The effects of a stellar encounter on a planetesimal disk
Abstract We investigate the effects of a passing stellar encounter on a planetesimal disk through analytical calculations and numerical simulations, and derive the boundary radius ( a planet )Expand
Growth of a Migrating Protoplanet
Abstract In the solar nebula, protoplanets may rapidly migrate to the Sun due to the tidal interaction with the nebula disk (e.g., Ward 1986, Icarus67, 164–180). We investigated the growth rate of aExpand
Accretional Evolution of a Planetesimal Swarm
We use our multi-zone simulation code (D. Spaute, S. Weidenschilling, D. R. Davis, and F. Marzari,Icarus92,147–164, 1991) to model numerically the accretion of a swarm of planetesimals in the regionExpand
Runaway Migration and the Formation of Hot Jupiters
We evaluate the coorbital corotation torque on a migrating protoplanet. The coorbital torque is assumed to come from orbit crossing fluid elements that exchange angular momentum with the planet whenExpand
Formation of planetary embryos: effects of fragmentation, low relative velocity, and independent variation of eccentricity and inclination.
An earlier investigation of the formation of approximately 10(26) g planetary embryos from much smaller planetesimals has been extended to include the effects of collisional fragmentation, the low relative velocity regime in which the effects due to solar gravity are important, and independent perturbations of eccentricity and inclination.

Velocity Evolution of Planetesimals: Unified Analytical Formulas and Comparisons with N-Body Simulations
Abstract Analytical formulas are derived for the rates of evolution of the mean square orbital eccentricities and inclinations of a general population of planetesimals. For planetesimals on crossingExpand
