Wolf-Rayet class stars are massive stars that are nearing the end of their life cycle and have moved out of their hydrogen-burning phase. They were once over 20 solar masses but now shed considerable amounts of material through solar wind. Their surface temperature can reach 200,000 K, so they appear a brilliant blue.

Supergiants are among the most massive and most luminous stars. They occupy the top region of the Hertzsprung–Russell diagram with bolometric absolute magnitudes between −5 and −12 and temperatures from about 3,500K to over 20,000K.

Supergiants have masses from 8 to 12 times the Sun (M) upwards, and luminosities from about 10,000 to over a million times the Sun (L). They vary greatly in radius, usually from 30 to 500, or even in excess of 1,000 solar radii (R). They are massive enough to begin core helium burning gently before the core becomes degenerate, without a flash, and without the strong dredge-ups that lower-mass stars experience. They go on to successively ignite heavier elements, usually all the way to iron. Also because of their high masses they are destined to explode as supernovae.
