A hypergiant is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds. The term hypergiant is defined as luminosity class 0 in t

…was used to describe P Cygni, S Doradus, η Carinae, and the Hubble-Sandage variables as a group in 1974. LBVs are massive unstable supergiant (or hypergiant) stars that show a variety of spectroscopic and photometric variation, most obviously periodic outbursts and occasional much larger eruptions. In their…
