Two-colour photometry for 9473 components of close Hipparcos double and multiple stars Using observations obtained with the Tycho instrument of the ESAHipparcos satellite, a two-colour photometry is produced for componentsof more than 7 000 Hipparcos double and multiple stars with angularseparations 0.1 to 2.5 arcsec. We publish 9473 components of 5173systems with separations above 0.3 arcsec. The majority of them did nothave Tycho photometry in the Hipparcos catalogue. The magnitudes arederived in the Tycho B_T and V_T passbands, similar to the Johnsonpassbands. Photometrically resolved components of the binaries withstatistically significant trigonometric parallaxes can be put on an HRdiagram, the majority of them for the first time. Based on observationsmade with the ESA Hipparcos satellite.
CCD measurements of visual double stars made with the 50 CM refractor of the Nice Observatory We present the measurements of 49 visual double stars made in 1997 withthe 50 cm refractor of the Nice Observatory (Table 1). A CCD camera wasattached to this refractor. Some new binaries discovered by Hipparcoshave been measured. The algorithm used for these measurements is basedon the adjustment of a tridimensional mathematical surface. Table 1 isalso available in electronic form at CDS viahttp://cdsweb.u-strasbg.fr/Abstract.html }
