Source publication WebUse the data to make an H-R diagram of the globular cluster. Put the r magnitude on the y-axis and the g-r color on the x-axis. Try to take stars only from the cluster. Stars that appear dramatically different may be at different distances along the same line of sight. You should also be careful not to ...
WebIt is now close to forty years that Globular Clusters (GCs) HR diagrams are used to derive the age of the oldest stars of the Galaxy, but today they provide a very complete test of … WebThe HR diagram for stage 6 appears to be very similar to that of a globular cluster. Thus, we can conclude that open clusters are young (usually a few tens of millions or hundreds of millions of years old), while globular …
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. This implies that ages of some globular clusters are close to that of the universe. 5. SUMMARY In the century since the bases of HR diagrams were ...
