Abstract:

The basic characteristics of stellar complexes and superassociations, as well as the differences between these kinds of gigantic groups of young stars, are discussed. The main difference is that superassociations are the result of induced (triggered) star formation, while the stars and clusters in stellar complexes develop as a result of the spontaneous processes typical of galactic gaseous disks.

Keywords: review; superassociation; stellar complexes
