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.

Four-color UVBY and H-beta photometry of high-velocity and metal-poor stars. I - The catalogue of observations
A catalog of four-color uvby and H-beta photometry for 711 high-velocityand metal-poor stars is given. The selection of the stars and theobserving and reduction techniques used to obtain these data arediscussed. The photometry has been transformed closely onto the standarduvby-beta system. The errors of the data have been estimated using bothinternal and external comparisons. The data are uniform over the sky;that is, there are no significant north-south differences. For the largemajority of stars the mean errors of V, m1, c1, and beta are less than +or - 0.008 mag, and the error of b-y is less than + or - 0.005 mag.Values of V, b-y and beta and rough photometric classifications aregiven for 63 red and/or evolved stars that fall outside the range of thephotometric transformations.

Radial velocities for selected southern high-velocity stars
Radial velocities for more than 100 southern high-velocity stars fromthe catalog of Buscombe and Morris (1958) are obtained by using bothdirect and image-tube UBV spectroscopy. The observational procedure anddata reduction technique are described. Two stars on the observing listare found to have enormous radial velocities and very weak metalliclines: LTT 2571, with a radial velocity of +346 km/s, and LTT 2625, witha radial velocity of +301 km/s. Other unusual objects discovered includeLTT 2813, which reaches over 100 kpc from the galactic center with anorbital eccentricity of 0.85, and LTT 8376, which travels about thegalactic center in a retrograde orbit with large energy. It is notedthat LTT 2813 and LTT 8376, as well as nearly all other objects on thelist, display normal or nearly normal metallic lines.
