October 2015: Médaille de bronze du CNRS décernée à Sébastien Fromang
July 2015: The COAST project has released the video of the Mario Flock 3D global MHD simulation
The movie shows the temperature fluctuations in a 3D global radiation MHD simulation of a stratified disk. This disk is fully turbulent as a result of the magneto-rotational instability (MRI). (Flock et al. 2013, A&A 560A 43F).
The run was performed on the curie cluster at TGCC using 1024 Intel XEON X7560 cores. The amount of data for the movie is around 4 Terabyte. The grid used for the movie was 512x128x3072 ~ 2 times 10^8 cells.
The simulation was performed using the PLUTO radiation MHD code, published in our work mentioned above: http://www.aanda.org/articles/aa/abs/2013/12/aa22451-13/aa22451-13.html Our project was financed by the ERC under the European Union’s Seventh Framework Programme (FP7/2007-2013) / ERC Grant agreement nr. 258729.
June 2015: Public release of the DUMSES-Hybrid code DUMSES-Hybrid is a free software to model astrophysical systems on CPUs and GPUs. It is a 3D hybrid MPI/OpenMP & MPI/OpenACC Eulerian second-order Godunov (magneto)hydrodynamic simulation code in cartesian, spherical and cylindrical coordinates, written in Fortran 90. It is developed in SAp by Marc Joos, Sébastien Fromang, Patrick Hennebelle, and Romain Teyssier, and distributed under a joint CeCILL-A & GNU/GPL license.
DUMSES-Hybrid is publicly available and can be downloaded at: https://sourcesup.renater.fr/projects/dumses/

for getting the avi versions can send a request to COAST@cea.fr (DCP format is also
available). February 3, 2012: PRL Cover Results obtained by COAST members
Thierry Foglizzo, Frédéric Masset,
Jérôme Guilet, and Gilles
Durand on the Shallow Water Analogue of the Standing Accretion Shock
Instability are published in Physical Review Letters and featured on the cover
of this week's edition. This work associates experimentation, numerical
simulations and perturbative computations. The
article and movies are available here. A two pages Viewpoint is published
in Physics. A news release of the SAp is available here. September 2011: The COAST
meetings are back ! With plenty of new members
joining the COAST project, it seems like a good moment to revive the COAST
meetings. The format we are anticipating is a monthly meeting during which one
of us will present his work (ongoing or published research). The idea is to
have informal presentations (~40 mn long) that would
stimulate discussions. If you have any announcements of general interest
(meetings, special events, etc...), these meeting will also be a good
opportunity to do so. May 2011: Romain
Teyssier receives the " Grand
