For most of a star’s life, ​ (a)   in the core produces ​ (b)   from ​ (c)   . A star in this stage is a ​ (d)   . For stars on the main sequence, temperature is directly related to brightness. A star is on the main sequence as long as it is able to balance the inward force of ​ (e)   with the outward force of nuclear fusion in its core. The more massive a star, the more it must burn hydrogen fuel to prevent gravitational collapse. Because they burn more fuel, more massive stars have higher temperatures. Massive stars also run out of hydrogen sooner than smaller stars do.
