How large is a white dwarf? What is its surface temperature?
What is a white dwarf composed of?
What happens to white dwarfs when they cool?
What happens to the core of a massive star after it evolves off the main sequence? How is it different than a one solar mass star?
How can HR diagrams of star clusters help us test theories of stellar evolution?
We believe some star clusters are very young (a few million years old) and some are very old (10 billion years old). How was this conclusion reached?
How does mass transfer between binary stars affect their evolution?
Draw an HR diagram. Sketch the evolutionary path of a one solar mass star from the main sequence until it becomes a white dwarf. Label the subgiant, red giant, horizontal branch, assymptotic giant, planetary nebula, and white dwarf stages.
