WebThe spectral types are (very roughly) indicated at the top of the diagram. The broad sweep of stars from upper-left to lower-right is called the main sequence, and is the site of Hydrogen burning. After stars on the main sequence exhaust their fuel they move off the main sequence and become giants (most of the giants seen in the diagram would have … WebAn O-type main-sequence star (O V) is a main-sequence (core hydrogen-burning) star of spectral type O and luminosity class V. 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
