Stability of Globular Clusters

Authors: Paul R. Gerber

It is shown that an isolated star cluster is a stable configuration. Separation of a single star from all the others would cost an amount of energy, that grows with the logarithm of its distance from the remaining rest. This is in contrast to the general opinion that such a cluster would eventually decay into small units. However, this conventional view is hardly ever mentioned, considering the fact that clusters have been found that are older than the (awkwardly supposed) age of the universe.
