متن کاملDisk-Planet Interactions During Planet Formation
The discovery of close orbiting extrasolar giant planets led to extensive studies of disk planet interactions and the forms of migration that can result as a means of accounting for their location. Early work established the type I and type II migration regimes for low mass embedded planets and high mass gap forming planets respectively. While providing an attractive means of accounting for clo...
متن کاملPlanet formation and protoplanetary dust
Planet formation is a very complex process through which initially submicron-sized dust grains evolve into rocky, icy, and giant planets. The physical growth is accompanied by chemical, isotopic, and thermal evolution of the disk material, processes important to understanding how the initial conditions determine the properties of the forming planetary systems. Here we review the principal stage...
متن کاملEarth and Terrestrial Planet Formation
The growth and composition of Earth is a direct consequence of planet formation throughout the Solar System. We discuss the known history of the Solar System, the proposed stages of growth and how the early stages of planet formation may be dominated by pebble growth processes. Pebbles are small bodies whose strong interactions with the nebula gas lead to remarkable new accretion mechanisms for...
متن کاملMigration and giant planet formation
X iv :a st ro -p h/ 04 03 57 4v 1 2 4 M ar 2 00 4 We extend the core-accretion model of giant gaseous planets by Pollack et al. ([1996]) to include migration, disc evolution and gap formation. Starting with a core of a fraction of an Earth’s mass located at 8 AU, we end our simulation with the onset of runaway gas accretion when the planet is at 5.5 AU 1 Myr later. This timescale is about a fac...
