Suppose you were handed two H-R diagrams for two different clusters: diagram A has a majority of its stars plotted on the upper left part of the main sequence with the rest of the stars off the main sequence; and diagram B has a majority of its stars plotted on the lower right part of the main sequence with the rest of the stars off the main sequence. Which diagram would be for the older cluster? Why?
What is the H-R diagram Main Sequence? I. The region where stars spend most of their lives. II The location of stars burning hydrogen to helium at their centres. III. The locus of points containing Red Giant stars. IV. The path followed by a star as it evolves from a protostar to a Red Giant. I II I and II I, II, and III All of I, II, III, and IV
Choose the two qualities that describe a star located in the lower right of the H-R diagram. a. hot b. cold c. bright d. faint
