Formation of Stellar Streams Due to the Decay of Star Clusters, OB Associations, and Galaxy Satellites

This paper presents a scenario of the evolution of OB associations and star clusters from formation to decay, in the process of which they turn into stellar streams moving in the disk and stellar “rings” around the galactic center. The scenario also includes the formation of stellar streams by galaxies absorbing their dwarf satellite galaxies. The simplest spatial kinematic models of evolution are constructed. It is shown that the stellar structures that appear in the models are similar to the observed stellar streams.
