Laboratoire Dynamique des Etoiles, des (Exo)-planètes, et de leur environnement

 

 

Dr. Allan Sacha Brun, chef du LDE3, présente le laboratoire en particulier les activités de recherche sur le Soleil, les interactions étoiles-planètes et le satellite Solar Orbiter

 

LES THEMATIQUES DE RECHERCHE

SOLAR STELLAR DYNAMICS
Simulations MagnétoHydrodynamiques du Soleil De par sa proximité, le Soleil a une influence forte et directe sur la Terre et notre société technologique. En particulier, son activité magnétique

 

STARS, PLANETS, AND THEIR ENVIRONEMENTS
Des chercheurs du Service d'Astrophysique du CEA-Irfu et de l’Université de Bonn (Allemagne) viennent de démontrer l'existence de champs magnétiques stables dans les régions non convectives des étoiles comme les couches externes des étoiles plus massives que le Soleil ou le cœur des étoiles de type solaire.

 

SEISMOLOGY
Les observations sismiques sont uniques car ce sont les seules qui permettent de sonder et d'étudier l'intérieur du Soleil (Héliosismologie) et des étoiles (Astérosismologie) .

 

SOLAR CAST
SolarCast a web portal dedicated to Solar Prediction . SolarPredict: A tool to forecast the the solar activity 11-yr cycle and to invert meridional circulation based on a solar dynamo model and a 4D var variational technique.
