ESO News

Une équipe d'astronomes a capturé, au moyen de l'instrument SPHERE installé sur le Très Grand Télescope de l'ESO, l'image de la toute première planète décrivant une orbite excentrée à l'intérieur d'un système d'étoiles triple. L'orbite d'une telle planète devrait être instable, au point de rapidement l'éjecter du système. Tel n'est toutefois pas le cas. Cette observation inattendue laisse supposer que l'existence de tels systèmes pourrait être plus fréquente que prévu. Les résultats de cette étude paraîtront au sein de l'édition en ligne de la revue Science du 7 juillet 2016.
