On the Formation Timescale and Core Masses of Gas Giant Planets

Numerical simulations show that the migration of growing planetary cores may be dominated by turbulent fluctuations in the protoplanetary disk, rather than by any mean property of the flow. We quantify the impact of this stochastic core migration on the formation timescale and core mass of giant planets at the onset of runaway gas accretion. For standard solar nebula conditions, the formation of Jupiter can be accelerated by almost an order of magnitude if the growing core executes a random… Expand

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
Planetesimal Accretion onto Growing Proto-Gas Giant Planets
The solar and extrasolar gas giants appear to have diverse internal structure and metallicities. We examine a potential cause for these dispersions in the context of the conventional sequentialExpand

The potential for Earth‐mass planet formation around brown dwarfs
Recent observations point to the presence of structured dust grains in the discs surrounding young brown dwarfs, thus implying that the first stages of planet formation take place also in theExpand
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
Accretion of terrestrial planets from oligarchs in a turbulent disk
Abstract We have investigated the final accretion stage of terrestrial planets from Mars-mass protoplanets that formed through oligarchic growth in a disk comparable to the minimum mass solar nebulaExpand
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 constrainedExpand

Gap Formation by Planets in Turbulent Protostellar Disks
The processes of planet formation and migration depend intimately on the interaction between planetesimals and the gaseous disks in which they form. The formation of gaps in the disk can severelyExpand

A Young White Dwarf Companion to Pulsar B1620-26: Evidence for Early Planet Formation
The color and magnitude of the stellar companion indicate that it is an undermassive white dwarf of age 480 × 106 ± 140 × 106 years, which places a constraint on the recent history of this triple system and supports a scenario in which the current configuration arose through a dynamical exchange interaction in the cluster core.
