A typical globular cluster might have > 10 5 stars, whereas a typical open cluster might have more like ∼ 10 3. This means the various features in the HR diagram are much better delineated in a globular cluster - the turn-off, a red giant branch and a horizontal branch.

WebMain sequence turnoff. HR diagrams for two open clusters, M67 and NGC 188, showing the main sequence turn-off at different ages. The turnoff point for a star refers to the point on the Hertzsprung–Russell diagram where it leaves the main sequence after its main fuel is exhausted – the main sequence turnoff . WebFor a given cluster, the shape of its HR diagram is influenced by many of the original gas cloud’s properties. Globular clusters are very old, at least two-thirds the age of the universe, which means they formed at a time when heavy elements were very sparse. They also tend to have short main sequences and long red giant branch. WebH–R diagram: (Hertzsprung–Russell diagram) a plot of luminosity against surface temperature (or spectral type) for a group of stars. main sequence: a sequence of stars on the Hertzsprung–Russell diagram, containing the majority of stars, that runs diagonally from the upper left to the lower right. rocky mountain power spanish
