Emergence of intense jets and Jupiter Great Red Spot as maximum entropy structures
F. Bouchet, J. Sommeria
We explain the emergence and robustness of intense jets in highly turbulent planetary atmospheres, like on Jupiter, by a general approach of statistical mechanics of potential vort…

DID PLANET FORMATION BEGIN INSIDE PERSISTENT GASEOUS VORTICES?
P. Barge, J. Sommeria
We explore here the idea, reminiscent in some respect of Von Weizsacker's (1944) and Alfven's (1976) outmoded cosmogonies, that long-lived vortices in a turbulent protoplanetary ne…
