Most of the stars occupy the region in the diagram along the line called the main sequence. During the stage of their lives in which stars are found on the main sequence line, they are fusing hydrogen in their cores. The next concentration of stars is on the horizontal branch (helium fusion in the core and hydrogen burning in a shell surrounding the core).

WebDepartment of Astronomy WebFor a young cluster, the HR diagram would show a more linear pattern called the main sequence, but as the more massive stars begin to cool, they move off of the main sequence line to become cooler and dimmer. As the cluster ages, one begins to see the less massive stars peeling off the main sequence as well. Thus, astronomers can determine the ... guardian childcare \u0026 education kinfolk alburyWebFor 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. guardian chingford news
