SUPERGIANT STAR
Supergiants are among the most luminous and massive stars, ranging between 7-10 solar masses and can range in brightness from thirty thousand to hundreds of thousands the output of our sun. They reside in the top region of the Hertzsprung-Russel diagram; having temperatures from 3,500k to over 20,000k and having bolometric absolute magnitudes between -5 and-12. Supergiants are massive enough to begin burning helium gently in their core before it becomes degenerate, and without the strong dredge-ups that lower-mass stars experience. They are able to go on successfully igniting heavier elements, usually all the way to iron.
These stars are classified into 2 specific groups; red and blue supergiants. Supergiants have very short
