from Ça Se Passe Là-Haut · host eric simon

Une équipe internationale confirme la cause de la forte baisse de luminosité de Bételgeuse durant l'hiver 2019-2020. C'est bien une grosse quantité de poussière que la supergéante rouge a produit et qui a obscurci une grande partie de son hémisphère sud. L'étude intitulée A dusty veil shading Betelgeuse during its Great Dimming est parue aujourd'hui dans Nature.
