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.
| A photometric study of wide visual double stars. II - Common proper motion double stars
A total of 82 common proper motion wide visual double stars have beenobserved using the uvby, H-beta systems. MK class, color excess,absolute magnitude, effective temperature, and distance have beenderived from calibrations of the above systems. From the distancesderived here and the astrometric data, taken from the literature, it wasfound that the percentage of physical binaries among the common propermotion wide double stars is significantly higher than the samepercentage among the wide visual double stars with significant relativeproper motion, but there are a lot of optical pairs among them as well.
| Photographic observations of visual double stars
The results of photographic observations of 199 visual double stars,obtained at the Bosscha Observatory at Lembang, Indonesia, in the years1958-1975 (with one 1953 plate) are presented. The material comprises708 plates with an average of 37 images measured per plate. A shortdescription of the program is given (cf. van Albada-van Dien, 1958).
