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. fig gmbh kölnWebThe H-R diagram of a young star cluster shows that low mass stars have not yet reached the main sequence yet.
