Hipparcos astrometry for 257 stars using Tycho-2 data
We present improved Hipparcos astrometry for 257 Hipparcos stars,resolved into 342 components. For 64 of the stars no astrometry wasobtained in the Hipparcos Catalogue, while for the remaining starsadditional components have been added by this solution or the positionshave been revised considerably. We have used the published Hipparcostransit data for the new solutions, together with results from thesecond reduction of the Tycho data for defining better initial values.Based on observations made with the ESA Hipparcos astrometry satellite.Table 3 is only available in electronic form at the CDS via anonymousftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.html

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.
