7. Why isn’t a brown dwarf a star? Why didn’t it reach the needed temperature?

8. What happens in a red giant to cause the core to shrink?

9.  You are analyzing the light from an unknown star. Specifically, you are analyzing the emission line of neon that is measured on the Earth at 654.5 nm (a unit of length). You find that the star emits that same neon line at 651.2 nm. What is the relative motion of the star and the earth?  Please choose one answer and explain why that is the correct answer. You will only get credit if you explain your answer. Please provide drawings.

• The star and the Earth are getting farther apart.
