Scientific paper

The results of observations of 159 stars at 1640 A in Puppis made with the space telescope 'Glazar' are presented. It is shown that the observed stars are members of different groups of stars situated at distances of about 120, 370, 700, 1250, 2400, and 4000 pc. The last two groups belong to the Pup OB1 and Pup OB2 stellar associations. There is relatively little absorption in the observed region. The absorbing matter is mainly concentrated in small clouds. It is suggested that three stars - CP - 27 deg 4197, HD 60479, and HD 61672 - are embedded in a dust envelope and that the star HD 60057 has a hot subdwarf companion. Forty-four of the observed stars are new OB or early A-type stars, spectral types of which were not known.
