Sophie Fuggle,Yari Lanci,Martina Tazziolied by Lynga and Palous (1987) to describe the local kinematics of open star clusters, and by Janes, Tilley, and Lynga (1988) to describe the general properties of the open cluster system. The galactic distribution of open clusters was discussed by Janes and Adler (1982).

Wolf-Rayet Starsontinuum in the optical region. Prominent emission lines from highly excited ions of helium, He, carbon, C, nitrogen, N, and oxygen, O, are used in their spectral classification (see accompanying table). There are two major subtypes of the WR stars; those dominated by lines of helium and nitrogen io

Globular Clustersn 10 and 22 billion years. These ages are rather uncertain and somewhat controversial. Petersen (1987) has tabulated the ages of many clusters in a self-consistent fashion, but the uncertainties of specific age estimates are large. Different authors obtain age estimates for the same globular cluster
