Planetary Migration in Resonance, the question of the Eccentricities : Les Houches contribution
A. Crida, Zs. Sándor, W. Kley
The formation of resonant planets pairs in exoplanetary systems involves planetary migration inside the protoplanetary disc : an inwards migrating outer planet captures in Mean Mot…
Migration of Protoplanets in Radiative Disks
Wilhelm Kley, Aurelien Crida
In isothermal disks the migration of protoplanets is directed inward. For small planetary masses the standard type-I migration rates are so fast that this may result in an unrealis…
Influence of an inner disc on the orbital evolution of massive planets migrating in resonance
A. Crida, Zs. Sándor, W. Kley
The formation of resonant pairs of planets in exoplanetary systems involves planetary migration in the protoplanetary disc. After a resonant capture, the subsequent migration in th…
Building Giant-Planet Cores at a Planet Trap
Alessandro Morbidelli, Aurelien Crida, Frederic Masset +1
A well-known bottleneck for the core-accretion model of giant-planet formation is the loss of the cores into the star by Type-I migration, due to the tidal interactions with the ga…
Dynamics of the giant planets of the solar system in the gaseous proto-planetary disk and relationship to the current orbital architecture
Alessandro Morbidelli, Kleomenis Tsiganis, Aurelien Crida +2
We study the orbital evolution of the 4 giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset and Snellgrove (2001) and Morbidelli…
The dynamics of Jupiter and Saturn in the gaseous proto-planetary disk
Morbidelli Alessandro, Aurelien Crida
We study the possibility that the mutual interactions between Jupiter and Saturn prevented Type II migration from driving these planets much closer to the Sun. Our work extends pre…
Cavity opening by a giant planet in a protoplanetary disc and effects on planetary migration
A. Crida, A. Morbidelli
We study the effect of a Jovian planet on the gas distribution of a protoplanetary disc, using a new numerical scheme that allows us to take into consideration the global evolution…
Simulating planet migration in globally evolving disks
A. Crida, A. Morbidelli, F. Masset
Numerical simulations of planet-disk interactions are usually performed with hydro-codes that -- because they consider only an annulus of the disk, over a 2D grid -- can not take i…
Surface density jumps as planet traps
F. Masset, A. Morbidelli, A. Crida +1
[Abridged] The tidal torque exerted by a protoplanetary disk with power law surface density and temperature profiles onto an embedded protoplanetary embryo is generally a negative…
On the width and shape of gaps in protoplanetary disks
A. Crida, A. Morbidelli, F. Masset
Although it is well known that a massive planet opens a gap in a proto-planetary gaseous disk, there is no analytic description of the surface density profile in and near the gap.…
