SANTIAGO 91, a right ascension catalogue of 3387 stars (equinox J2000).
The positions in right ascension of 3387 stars belonging to the Santiago67 Catalogue, observed with the Repsold Meridian Circle at Cerro Calan,National Astronomical Observatory, during the period 1989 to 1994, aregiven. The average mean square error of a position, for the wholeCatalogue, is +/-0.009 s. The mean epoch of the catalogue is 1991.84.
| Ultraviolet observations in Puppis with the space telescope 'GLAZAR'
The results of observations of 159 stars at 1640 A in Puppis made withthe space telescope 'Glazar' are presented. It is shown that theobserved stars are members of different groups of stars situated atdistances of about 120, 370, 700, 1250, 2400, and 4000 pc. The last twogroups belong to the Pup OB1 and Pup OB2 stellar associations. There isrelatively little absorption in the observed region. The absorbingmatter is mainly concentrated in small clouds. It is suggested thatthree stars - CP - 27 deg 4197, HD 60479, and HD 61672 - are embedded ina 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.
| VBLUW-photometry of stars in small fields around 13 planetary nebulae
Observations of stars in small fields around 13 planetary nebulae, madeusing the Walraven five-channel VBLUW photometer, are presented anddescribed. The fields are found to have a radius of about 0.3 deg. Thefinding charts for the measured stars are given. It is shown that moststars are brighter than mV of about 14 mag and that the photometry hasan accuracy of better than 1 percent, except for stars that are observedwith short test-integrations and for stars fainter than mV of about 14mag. The photometric data for all stars are presented, together with alist of identifications and spectral types.
