Stellar associations in the region of CMa.
Abstract
Forty-three early-type stars brighter than 9 mag at 1640 A were observed in the region of CMa with the Glazar Space Telescope. The observed stars are shown to compose three groups situated at distances of 320, 570, and 1100 pc. The first two groups are B-associations, and the third is an O-association. It is concluded that the dust matter situated at distances up to 1000 pc yields an interstellar extinction parameter of 0.7 mag at 1640 A.
