Ganym\u00e8de est la plus grande lune de Jupiter ainsi que la plus grande et la plus diff\u00e9renci\u00e9e du syst\u00e8me solaire. Son int\u00e9rieur contient un noyau m\u00e9tallique \u00e0 l\u2019origine d\u2019une dynamo op\u00e9rant aujourd\u2019hui ainsi qu\u2019un oc\u00e9an d\u2019eau liquide sous la cro\u00fbte de glace qui implique des questions cl\u00e9s li\u00e9es \u00e0 son habitabilit\u00e9. En raison de ces attraits, la mission ESA JUICE, avec un lancement le 13 avril 2023, atteindra Jupiter en 2031 puis entamera en 2034 une phase enti\u00e8rement consacr\u00e9e \u00e0 la caract\u00e9risation de Ganym\u00e8de comme corps plan\u00e9taire embl\u00e9matique. Les missions NASA Europa Clipper et Dragonfly consacr\u00e9es \u00e0 Europe, une lune voisine, et Titan, une lune de Saturne avec une taille comparable \u00e0 Ganym\u00e8de, ont une \u00e9ch\u00e9ance temporelle comparable. Il est essentiel d\u2019\u00e9tablir en amont de ces missions les chemins d\u2019\u00e9volution emprunt\u00e9s par ces mondes oc\u00e9ans de grande taille d\u00e8s lors que les mod\u00e8les sont rares et incomplets. Bien que la formation du syst\u00e8me de Jupiter soit encore d\u00e9battue, il semble av\u00e9r\u00e9 que les lunes galil\u00e9ennes suivent une \u00e9volution plus froide, et donc plus lente, que celle des plan\u00e8tes telluriques. Pour ces derni\u00e8res, les \u00e9coulements multiphasiques sont associ\u00e9s soit \u00e0 des \u00e9v\u00e8nements \u00e0 l\u2019\u00e9chelle globale qui interviennent tr\u00e8s t\u00f4t dans leur histoire sur une \u00e9chelle de temps limit\u00e9e, soit \u00e0 des ph\u00e9nom\u00e8nes plus locaux telles que ceux qui interviennent dans la g\u00e9odynamique actuelle des dorsales m\u00e9dio-oc\u00e9aniques sur Terre. Un focus est mis sur la diff\u00e9renciation diphasique de Ganym\u00e8de ou d\u2019autres lunes g\u00e9antes dans un contexte de r\u00e9chauffement graduel par d\u00e9sint\u00e9gration radioactive : cela inclut une phase de d\u00e9shydratation qui peut conduire \u00e0 la formation d\u2019une hydrosph\u00e8re volumineuse ainsi que, plus tard, pour des temp\u00e9ratures plus \u00e9lev\u00e9es, \u00e0 la formation du noyau. D\u00e8s lors que de tels ph\u00e9nom\u00e8nes sont lents et globaux, ils ne peuvent \u00eatre isol\u00e9s comme des phases ind\u00e9pendantes. Ils contribuent \u00e0 l\u2019histoire \u00e0 grande \u00e9chelle de la lune et peuvent conduire, par exemple, \u00e0 des \u00e9v\u00e8nements g\u00e9ologiques majeures de la cro\u00fbte de glace ou bien \u00e0 l\u2019\u00e9tablissement de la dynamo actuelle. L\u2019objectif est de simuler num\u00e9riquement la diff\u00e9rentiation de Ganym\u00e8de, d\u2019une part la diff\u00e9rentiation hydrosph\u00e8re\/roche puis la diff\u00e9renciation roche\/noyau riche en fer<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
