Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an
Ping Chen, Avishay Gal-Yam, Subo Dong +14
We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…
