Learning Goals

By the conclusion of this chapter, you should be able to:
  1. Make a flowchart of the stages of evolution for high-mass stars.
  2. Describe how the death of high-mass stars differs from that of low-mass stars.
  3. Explain the origin of chemical elements up to and heavier than iron.
  4. Identify how H-R diagrams enable astronomers to measure the ages of stars and test theories of stellar evolution.

Prepare and Assess


    1. The CNO Cycle
      Section: 17.1
    1. H-R Diagram Cluster Fitting Explorer
      Try fitting different clusters onto the H-R Diagram to see how knowing both the absolute and apparent magnitude of the main sequence turn off allows you to find the distance to the cluster.
