Astronomers can spend entire careers studying specific types of stars. If you could choose one kind of star or one area of the H-R Diagram on which to focus, what would you choose, and why? Do you consider your chosen area interesting? Important?
Deneb is an interesting star because it is classified as a "super giant". I think super giants are unique because they are so massive. The Super Giants in the H-R diagram range from extremely hot to very mild temperature. I think the differences in their temperature and the age of the stars would be an important area of study.
