from Ça Se Passe Là-Haut · host Eric Simon

Une équipe d’astrophysiciens brésiliens a évalué l'effet combiné de l'âge et de la masse stellaire sur l'abondance du Lithium dans un échantillon de 153 étoiles de type solaire dont 74 nouvelles étoiles. Ils trouvent une incompatibilité avec les modèles stellaires standards. L’étude est publiée dans Monthly Notices of the Royal Astronomical Society.https://www.ca-se-passe-la-haut.fr/2023/09/le-lithium-du-soleil.html Source Lithium depletion in solar analogs: age and mass effectsAnne Rathsam et al.Monthly Notices of the Royal Astronomical Society 525 (31 august 2023)https://doi.org/10.1093/mnras/stad2589
