Spectral Classification in Some Open Clusters.
Abstract
Spectral types and luminosities of 50 stars in the open clusters NGC 1342, 6755, 6802, 6882, 6885, 6940, 7031, 7209, and 7686 were obtained, and spectroscopic distances of these clusters were derived. Comparison of these spectroscopic data with the photoelectric data is discussed.
