Rationale

The hydrodynamics of the stellar interior where multiple fluids are participating in convective and other mixing and nuclear reaction processes is a rich, emerging cross roads area of research, connecting multiple interests in academia and at the labs. Many discrepancies exist between stellar astrophysical observables and predictions of existing simplified and often one-dimensional models of complex fluid-flow problems. These are now beeing addressed by constructing realistic multi-dimensional simulations of the important processes involved e.g., turbulent entrainment, multi-fluid mixing, interaction of reactive and hydrodynamic processes. These astrophysical problems are highly relevant for interpreting observation, yet at the same time provide opportunities for alternative code verification and validation.

Format and venue

The stellar hydro days meeting follows the pattern established at last year's meeting: informal presentations and lots of time for open discussion. The meeting will take place in the Avanza Technologies meeting room in the Research Park building on the same floor as the Hot Rocks Cafe. Wired internet connection will be available in the meeting room. Wireless is availbale in the Hot Rocks Cafe. The contact person for the meeting room is Monica from Avanza Technologies, who can help you if you absolutely can not find the room. How to get to the venue: Directions to the Avanza Technical Facility are: 2nd Floor, Room 202A, (diagonally across from the elevators). Here is a map how to get to Los Alamos Research Park.
