(you find the presentation linked to the headline and the videos below the abstract if available)

Dates: 14th - 18th June 2011
Location: Ringberg Castle, Bavaria

In recent years we learned that the Baroclinic Instability (B.I.) that shapes the atmospheric circulations and the weather pattern on our home planet can also be operative in the solar nebula, e.g. the accretion disk around the young sun in which the earth has formed more than 4 Billion years ago. The investigation of the nature of this B.I. has the power to renew the traditional fruitful interactions between the astrophysical and geophyscial communities. This conference shall provide the platform to learn about the similarities and differences between the B.I. in the solar nebula vs. earth atmosphere and the ocean. It shall introduce the astrophysicists to the comprehensive amount of analytic, numeric and experimental work in the geophysical and meteorological community. In return the astronomical and astrophysical knowledge about the properties of disks around young stars and planet formation processes within shall be displayed and contrasted to the conditions on planet earth and in the laboratory.

The limitation of the workshop to 48 participants and the unique location of Ringberg Castle will provide the ambiance for discussion and close interaction among all participants.

The aim of the workshop is to learn from each other, to foster new collaborations and to define questions to be answered on the B.I. in the context of accretion disks and planet formation via refined analytic work, numerical simulations and ultimately via laboratory experiments.

A sample for burning questions about B.I. in accretion disks:
  • What are the precise conditions for B.I. to occur?
  • Will it start spontaneously or does it need a trigger?
  • Do disk vortices radiate gravity waves and is this interaction comparable to Rossby waves and gravity waves in hurricanes?
  • How strong can it be in terms in angular momentum transport?
  • Will the B.I. survive in disks where also magnetic turbulence can occur?
  • What are the implications of B.I. on the formation of planets from planetesimal formation to migration of giant planets?
  • Can we build experiments to study B.I. in the presence of shear?
