#1547 : Découverte de 6 destructions explosives de naines blanches par des trous noirs massifs

from Ça Se Passe Là-Haut · host Eric Simon

Un duo d’astrophysiciens américains vient de trouver 6 supernovas de type Ia atypiques. Elles auraient été déclenchées à cause du trop fort rapprochement d’une naine blanche d’un trou noir très massif, mais pas supermassif. Ils publient leur découverte dans The Astrophysical Journal.https://www.ca-se-passe-la-haut.fr/2023/09/decouverte-de-6-destructions-explosives.html Source The Search for Thermonuclear Transients from the Tidal Disruption of a White Dwarf by an Intermediate-mass Black HoleSebastian Gomez and Suvi GezariThe Astrophysical Journal, Volume 955, Number 1 (15 september 2023)https://doi.org/10.3847/1538-4357/acefbc Illustrations Courbes de lumière et localisation des 6 candidates TDE Ia (Sebastian Gomez and Suvi Gezari) Suvi Gezari Sebastian Gomez
