O-type main-sequence star
Stellar classification
An O-type main-sequence star is a main-sequence—core hydrogen-burning—star of spectral type O. The spectral luminosity class is V, although class O main sequence stars often have spectral peculiarities due to their extreme luminosity. These stars have between 15 and 90 times the mass of the Sun and surface temperatures between 30,000 and 50,000 K. They are between 40,000 and 1,000,000 times as luminous as the Sun.
