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, a question that shares significant similarities with the study of stratified and rotating two-phase flows in fluid mechanics.The goal of the workshop is to discuss the recent developments in the field, focusing on:
  • the possible formation of gaseous structures in the protoplanetary disks, particularly in the dead-zone, under various instabilities (baroclinic or barotropic via Rossby or edge modes),
  • their lifetime and evolution (stability, migration, collisions ....),
  • their ability to capture the solid material and to survive once loaded against other instabilities,
  • their consequences on the global disc evolution.

• Emphasis will be placed on the hydrodynamical aspects of the problem but MHD processes will not be forgotten. The importance of 3D and self-gravity will be stressed. Part of the meeting will be also devoted to discuss 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.
