Most studies of convection rely on approximate models of the governing equations: Boussinesq or other sound-proof models, anelastic, pseudo-incompressible... In the geophysical and astrophysical contexts, it is difficult to decide which model is most appropriate and the answer may depend on the particular scientific question under scrutiny. During this conference, we will discuss the limits and applicability of any model of convection in any of the diverse forms of convection: it may be driven by thermal, compositional, phase change or magnetic buoyancy effects. We will also consider compressibility effects in stably stratified cases and their impact on internal gravity, inertial or Alfven waves. In summary, all contributions about the limitations, failure or improvements of convection models are welcome, from an observational, experimental, numerical or theoretical point of view.

A one-page summary must be submitted in the "Submit an abstract" section to request an oral presentation. The attendees to the conference will be free to bring posters, that will be displayed as a support for informal discussions. Similarly, attendees will be free to participate to the "numerics" or "experiments" workshops.

250 euros  (200 early-bird) for lecturers, professors. 125 euros (100 early-bird) for post-docs, PhDs.

Dinner: 40 euros (lect, prof) 20 euros (PhD, Post-Doc)

The conference will take place on the university campus La Doua  (Darwin building), near the "Parc de la tête d'or". Stop at "Universite Lyon1" on the T1 tram line. Usually, from anywhere in the city of Lyon, the quickest way is to take a metro to the stop "Charpennes" on lines A and B, and to complete the journey with tram T1. This means that we do not recommend specific locations or hotels for accommodation.
