<P> In general , the more massive a star is , the shorter its lifespan on the main sequence . After the hydrogen fuel at the core has been consumed , the star evolves away from the main sequence on the HR diagram . The behavior of a star now depends on its mass , with stars below 0.23 M becoming white dwarfs directly , whereas stars with up to ten solar masses pass through a red giant stage . More massive stars can explode as a supernova , or collapse directly into a black hole . </P>
