"Instabilities and Structures in Proto-Planetary disks"

Dates: 17-20 september 2012.

Location: Marseille city - 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.
