you can find on both lists.
2. Are the nearest stars ALWAYS the brightest? Is the list on the left the same as the right?
3. A star located in the lower right portion of the HR Diagram is cool and dini. What are the
characteristics of a star in the upper left?
What about the stars in the upper right?
4 Look on page 819 of the textbook, in which group do most of the stars belong?
5. According to your diagram, are any of these stars white dwarfs? Explain how you know.
6. In order to be a star, it must burn gas through a process called fusion. What is fusion?
