As the star gets bigger the density decreases and the gravitational force is getting weaker.
Star gets bigger, brighter and cooler |

Ends Giant Phase. Anything less than 8 Mass is Low Mass, anything greater than 8 Mass is High Mass. The temperature
needed for hydrogen fusion is 10,000,000 kelvin, for helium fusion 10,000 kelvin is needed. |

Term
|
Definition
when the helium fusion begins, it becomes unstable
This disturbance causes the fluid within the star to move towards the outer edge which
causes problems |

Term
|
Definition
o High mass stars are more stable
o A high mass star goes through several additional fusion products
o The final product of helium fusion is carbon. Carbon builds up around the core, and then it
starts to fuse. |

While the star is collapsing, the outward pressure is decreasing and the inward pressure is
increasing; this causes the star to explode, |
