| FORMATION ET ÉVOLUTION DES SYSTÈMES PLANÉTAIRES ET EXTRASOLAIRES (en Français) | |||
Droits : Droits réservés à l'éditeur et aux auteurs Auteur(s) : LAGRANGE Anne-Marie, MOUETTE Jean 30-03-2012 Description : Since the discovery of an extended disk of dust around beta Pictoris in the late 80's, this system has been intensively observed and modeled, in connection with planetary system formation/evolution. The presence of planets has been proposed over 2 decades to explain various observations, and high angular resolution imaging allowed us recently to directly image a planet orbiting about 9 AU from the star, this is so far the closest extrasolar planet imaged. I will present a brief overview of the main indirect signatures of planets around the star, and describe our recent results on beta Pictoris b characterization, as well as its connection to the dust disk. I will also present the current knowledge on the presence of other planets around the star, using several complementary detection technics. This single system gives already interesting information/constraints about giant planet formation and evolution. I will describe how forthcoming high angular resolution imagers such as Sphere on the VLT will improve our knowledge on giant planet characteristics and help further constraining giant planet formation scenarios.
