The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves

M. Kopsacheili, L. Galbany, G. Folatelli +32

We present observations of the 1991bg-like type Ia supernova (SN) 2023vjh, associated with the elliptical galaxy MCG+04-10-013. Its light-curve shape parameters ($Δm_{15}(B)=1.89…
