Halting Type I planet migration in non-isothermal disks
Aims. We investigate the effect of including a proper energy balance on the interaction of a low-mass planet with a protoplanetary disk. Methods. We use a three-dimensional version of the RODEO method to perform hydrodynamical simulations including the energy equation. Radiation is included in the flux-limited diffusion approach. Results. The sign of the torque is sensitive to the ability of th...
متن کاملHalting Planet Migration in the Evacuated Centers of Protoplanetary Disks
Precise Doppler searches for extrasolar planets find a surfeit of planets with orbital periods of 3–4 days, and no planets with orbital periods less than 3 days. The circumstellar distance, R0, where small grains in a protoplanetary disk reach sublimation temperature (∼ 1500 K) corresponds to a period of∼ 6 days. Interior to R0, turbulent accretion due to magneto-rotational instability may evac...
متن کاملType I Planet Migration in Nearly Laminar Disks
We describe 2D hydrodynamic simulations of the migration of low-mass planets (≤ 30M⊕) in nearly laminar disks (viscosity parameter α < 10 ) over timescales of several thousand orbit periods. We consider disk masses of 1, 2, and 5 times the minimum mass solar nebula, disk thickness parameters of H/r = 0.035 and 0.05, and a variety of α values and planet masses. Disk selfgravity is fully included...
متن کامل00 9 On the horseshoe drag of a low - mass planet . I - Migration in isothermal disks
We investigate the unsaturated horseshoe drag exerted on a low-mass planet by an isothermal gaseous disk. In the globally isothermal case, we use a formalism, based on the use of a Bernoulli invariant, that takes into account pressure effects, and that extends the torque estimate to a region wider than the horseshoe region. We find a result that is strictly identical to the standard horseshoe d...
متن کاملType I Migration in a Non-isothermal Protoplanetary Disk
We calculate rates of Type I migration of protoplanets in a non-isothermal three-dimensional protoplanetary disk, building upon planet-disk models developed in previous work. We find that including the vertical thickness of the disk results in a decrease in the Type I migration rate by a factor of ∼ 2 from a two-dimensional disk. The vertical temperature variation has only a modest effect on mi...
