. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.

... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ...
