Instabilities and Structures in Proto-Planetary disks
Meeting
Dates: 17th - 20th september 2012
Location: Salle de l'Académie - Les Accoules - Marseille - France
Rationale:
- The meeting will address the evolution of the protoplanetary disks at the decoupling stage. The goal is to focus on:
- the possible formation of gaseous structures in the protoplanetary disks, particularly in the dead-zone, under various instabilities (baroclinic, or via Rossby or edge modes)
- their lifetime and evolution (stability, migration, collisions ....),
- their ability to capture the solid material and to survive once loaded.
- Emphasis will be placed on the hydrodynamical aspects of the problem, without and with self-gravity, but MHD processes will not be forgotten. We will look also at the links with the experimental and numerical works performed in the physics of rotating flows and granular media.
- The burning center of the discussions will be the possible (or impossible) routes toward planetesimals and planetary cores.
