Star Evolves

You probably know people with a Type A personality— they are always keyed up, hyper, superoverachievers, and you may even call them workaholics. These people often make it big, only to burn out quickly. Then there's the Type B personality: the kind of person who moves through life calmly, doing what's necessary, but no more. These people might not be very spectacular, but as with that tortoise in the fable, slow and steady sometimes wins the race.

Stellar careers are similar, though the letters of the alphabet used to label them are different. The massive, hot O and B stars are born, mature, and enter the main sequence, only to burn out, their hydrogen fuel exhausted, after a few million years. They are the gas-guzzlers of the galaxy. In contrast, the red dwarfs, stars of type M, low in mass and low in energy output, may not have as much fuel, but they will burn for hundreds of billions of years. Low-mass stars are econo-boxes. They are not as flashy as their more massive cousins, but you don't see their steaming hulks by the side of the road, either.
