Resources for the "H-R Diagrams of Star Clusters" lab

• The HR diagram (intro course)
• The HR diagram (intermediate course)
• Luminosity classes and the HR diagram (advanced course)

All the stars in a cluster are born at the same time, but some will age more rapidly than other. As a result, the HR diagram of stars in a cluster will change over time.

• Interpreting the HR diagram of stellar clusters
• Stellar lifecycles and the HR diagram
• You can use some applets to watch the HR diagram of a cluster change as the stars age. Look at the second half of this lecture
  • Watch a single star evolve
  • Watch an entire cluster evolve
