WebThe main sequence turno for this globular cluster is at a color index of about (B V) = 0.4, the color of F stars. An F star has a mass of about 1.5 M Sun, thus stars with masses near 1.5 M Sun are evolving o the main sequence to become red giants, so this globular cluster is about 7 billion years old. Figure 4: The HR diagram for the globular ... WebGlobular clusters are much older than open clusters. When plotted on an HR diagram, they typically have no remaining O, B, A, F class main sequence stars, and their turnoff occurs in the G class.
