#1759 : L'atmosphère d'une mini-Neptune dévoile son histoire migratoire

from Ça Se Passe Là-Haut · host Eric Simon

De nouvelles mesures portant sur une Jupiter chaude et sur sa compagne de type mini-Neptune indiquent que ces deux exoplanètes se seraient formées à des distances notablement plus grandes de leur étoile hôte que ne le suggère leur configuration actuelle. L'étude est parue dans The Astrophysical Journal Letters.
