SN 2022ngb is a faint and slow-evolving Type IIb supernova, observations reveal

An international team of astronomers has conducted optical and near-infrared observations of a supernova designated SN 2022ngb. As a result, it was found that SN 2022ngb is a faint and slow-evolving Type IIb supernova with a low-mass envelope. The new findings were presented Dec. 10 on the arXiv preprint server.
