The discovery and study of stellar associations by Ambartsumian (1947, 1954 a) proved two fundamental points regarding the star formation process, e.g., Mirzoyan, 1976. One of them is that the formation process still continues in the present evolution of the Galaxy, and this thesis is not disputed now. According to the second, stars form as physical groups of multiple stars and star clusters, which become stellar associations during the initial phases of their evolution.
