and generally has a shorter but more dramatic life. a star of ten solar masses, for example, would burn fuel at about a thousand times the rate of the sun, and would exhaust its hydrogen fuel in less than 100 million years (compared to the sun's 10 billion year lifetime). a star 20 times the mass of our sun would burn its fuel 36,000 times faster than the sun, and might live only a few million years in total.
larger stars are much hotter and the higher temperatures within such a star are sufficient to fuse even helium. the helium then becomes the star's raw fuel, and it goes on to
