WebIn M13's HR diagram, the stars clearly fall into distinct groups. The broad swath extending diagonally from the bottom right is the cluster's main sequence. A sharp turn toward the upper right hand corner follows the red giant branch while the blue giants are found grouped in the upper left. WebFeatures of the expected H-R diagram for one solar mass appear clearly in the M80 H-R diagram the red-giant, horizontal-branch, and asymptotic-giant-branch stars in M80 are all roughly one solar mass. Blue stragglers. A few blue stragglers appear in the M80 H-R diagram. Why didn't these more massive stars evolve to white dwarfs long ago?
