A 91bg-like supernova fainter than any of its class raises new questions about thermonuclear explosions An international team has reported detailed optical and near-infrared observations of SN 2023vjh, a peculiar 91bg-like Type Ia supernova in the elliptical galaxy MCG+04-10-013. The object is unusually faint even for its already-subluminous subclass, and its excess reddening cannot be explained by dust along the line of sight — pointing to possible circumstellar material surrounding the progenitor white dwarf.... https://skycr.org/2026/07/20/sn-2023vjh-peculiar-91bg-like-supernova-unusually-faint/
