We analyze the orbital and mass evolution of planets that undergo runaway gas accretion by means of two- and three-dimensional hydrodynamic simulations. The disk torque distribution per unit disk mass as a function of radius provides an important diagnostic for the nature of the disk-planet interactions. We present results of simulations for mass-gaining, migrating planets. For planets with an initial mass of 5 M⊕, which are embedded in disks with standard parameters and which undergo runaway… Expand
Final Masses of Giant Planets. III. Effect of Photoevaporation and a New Planetary Migration Model
We herein develop a new simple model for giant planet formation, which predicts the final mass of a giant planet born in a given disk, by adding the disk mass loss due to photoevaporation and a newExpand
Gas accretion onto a protoplanet and formation of a gas giant planet
We investigate gas accretion on to a protoplanet, by considering the thermal effect of gas in three-dimensional hydrodynamical simulations, in which the wide region from a protoplanetary gas disc toExpand
Planet-Disk Interaction and Orbital Evolution
As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum and migration of the planet.Expand
MIGRATION OF PLANETS EMBEDDED IN A CIRCUMSTELLAR DISK
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
Migration of accreting planets in radiative discs from dynamical torques
We present the results of hydrodynamical simulations of the orbital evolution of planets undergoing runaway gas accretion in radiative discs. We consider accreting disc models with constant mass fluxExpand
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
Capture and Evolution of Planetesimals in Circumjovian Disks
We study the evolution of planetesimals in evolved gaseous disks, which orbit a solar-mass star and harbor a Jupiter-mass planet at a_p~5AU. The gas dynamics is modeled with a three-dimensionalExpand
Fast migration of low-mass planets in radiative discs
Low-mass planets are known to undergo Type I migration and this process must have played a key role during the evolution of planetary systems. Analytical formulae for the disc torque have beenExpand
Gas accretion on to planetary cores: three-dimensional self-gravitating radiation hydrodynamical calculations
We present results from three-dimensional, self-gravitating radiation hydrodynamical models of gas accretion by planetary cores. In some cases, the accretion flow is resolved down to the surface ofExpand
Final Masses of Giant Planets II: Jupiter Formation in a Gas-Depleted Disk
Firstly, we study the final masses of giant planets growing in protoplanetary disks through capture of disk gas, by employing an empirical formula for the gas capture rate and a shallow disk gapExpand
