Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

... Close," however, is only relative to other clusters of galaxies , since light takes about 50 million years to reach us from A2199. All of the fuzzy objects in the above picture are galaxies , but these galaxies do not contain most of the matter in the cluster. By studying clusters like A2199, astronomers conclude that some form of dark matter dominates the motion of the bright galaxies. ... Publications with keywords: galaxy cluster .
