Abstract
We present a method capable of determining the evolutionary stage of bound, isolated systems of galaxies. In particular, we shall apply it to a sample of groups, belonging to the Local Supercluster, taken from the Geller and Huchra’s (1983) Catalogue. The knowledge of the evolutionary stage of a system of galaxies is interesting in the framework of theories concerned with the formation of large-scale structures in the universe. Moreover, if one knows the evolutionary stage, it is possible, at least in principle, to determine the mass of the system even when it is not in virial equilibrium, as well as to infer some properties of its initial condition.
