Extreme red stars in in Cygnus.
Abstract
Results are presented of a photographic survey for infrared stars in several fields in Cyg and of photoelectric measurements on a sample of extremely red stars. About 400 new infrared stars were discovered. These stars are concentrated to the galactic plane. The reddened stars are correlated with dark clouds (field 95 - 0) and with strong H U regions (field 78 - 0). Some infrared stars seem to be highly reddened 0 stars, and possibly the until now unknown excitation strs of some H U regions. Key words: infrared stars - interstellar reddening
