Number each question

1. If someone asked you to compile a list of the nearest stars to the sun based on your own observations, what measurements would you make, and how would you analyze them to detect nearby stars? (From NJ)

2. Explain how the Hertzsprung-Russell diagram is constructed of the four main groupings of stars. Identify characteristics of the four main groupings of stars on the diagram.

3.”A Star is Born!” In a step-by-step fashion, reconstruct the birth of a star. In your answer, include interstellar medium, protostar, and how stellar equilibrium is finally reached.

4. “A Star Dies!” Using the same technique you applied in question 2 above, trace the elements in the demise of stars of low stellar mass, those of medium stellar mass, and those that are very massive.

5 Explain how Type I and Type II supernovae occur.
