Fate of high mass stars
After Helium exhausted, core collapses again until it becomes hot enough to fuse Carbon into Magnesium or Oxygen.
Through a combination of processes, successively heavier elements are formed and burned.
Notes:
After the red giant stage, there is a series of collapses and further nuclear burning. Fusion creates heavy elements from light elements.
This part introduces elements made in high mass stars. The next few slides do this, then we do Jim’s activities, and THEN we go on to neutron stars and BHs.
