O-type stars are hot and luminous. They have characteristic surface temperatures ranging from 30,000 to 52,000 K, emit intense ultraviolet light, and so appear in the visible spectrum as bluish-white. Because of their high temperatures the luminosities of main sequence O-type stars range from 10,000 times the Sun to around 1,000,000 times, giants from 100,000 times the Sun to over 1,000,000, and supergiants from about 200,000 times the Sun to several million times.
