Definition:

A high luminosity star with absolute visual magnitude around -10, about 10^6 times as luminous as the Sun. Hypergiant stars are evolved massive stars belonging to the luminosity class Ia+ or Ia0. Their spectra show very broadened emission and absorption lines resulting from the high luminosity and low surface gravity which favor strong stellar wind.
