A recipe for eccentricity and inclination damping for partial gap opening planets in 3D disks
Gabriele Pichierri, Bertram Bitsch, Elena Lega
In a previous paper we showed that, like the migration speed, the eccentricity damping efficiency is modulated linearly by the depth of the partial gap a planet carves in the disk…
Quasi-static contraction during runaway gas accretion onto giant planets
Michiel Lambrechts, Elena Lega, Richard P. Nelson +2
Gas-giant planets, like Jupiter and Saturn, acquire massive gaseous envelopes during the approximately 3 Myr-long lifetimes of protoplanetary discs. In the core accretion scenario,…
The reflex instability: exponential growth of a large-scale mode in astrophysical discs
Aurélien Crida, Clément Baruteau, Jean-François Gonzalez +5
We report the finding of a linear, non-axisymmetric, global instability in gas discs around stars, which may be relevant to other astrophysical discs. It takes the form of an …
Highly inclined and eccentric massive planets I: Planet-disc interactions
Bertram Bitsch, Aurélien Crida, Anne-Sophie Libert +1
In the Solar System, planets have a small inclination with respect to the equatorial plane of the Sun, but there is evidence that in extrasolar systems the inclination can be very…
On inertial forces (indirect terms) in problems with a central body
Aurélien Crida, Clément Baruteau, Philippine Griveaud +14
Gravitational systems in astrophysics often comprise a body -- the primary -- that far outweights the others, and which is taken as the centre of the reference frame. A fictitious…
Global 3D radiation-hydrodynamic simulations of gas accretion: The opacity dependent growth of Saturn-mass planets
Matthäus Schulik, Anders Johansen, Bertram Bitsch +1
The full spatial structure and temporal evolution of the accretion flow into the envelopes of growing gas giants in their nascent discs is only accessible in simulations. Such simu…
