Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.

Duflot, M.; Figon, P.; Meyssonnier, N.

We give a common version of the two catalogues of Mean Radial Velocities by Wilson (1963) and Evans (1978) to which we have added the catalogue of spectroscopic binary systems (Batten et al. 1989). For each star, when possible, we give: 1) an acronym to enter SIMBAD (Set of Identifications Measurements and Bibliography for Astronomical Data) of th…

Mesures de vitesses radiales. VII. Accompagnement AU sol du programme d'observation du satellite Hipparcos. Radial velocities. VII. Ground based measurements for Hipparcos.

Duflot, M.; Burnage, R.; Genty, V. +2 more

We publish 734 radial velocities of stars distributed in 28 fields of 4x4deg. We continue the PPO series (Fehrenbach et al. 1987; Duflot et al. 1990 and 1992), using the Fehrenbach objective prism method.

Astrometry of 19 globular clusters.

Johnston, H. M.; Picard, A.

We present accurate positions for the center of 19 globular clusters, 8 of which are known to contain X-ray sources and/or pulsars. The positions are based on a new centroiding algorithm applied to CCD images of the clusters. The fundamental astrometry is performed with plates from the ESO Schmidt telescope, using the Hipparcos Input Catalogue as …

CCD astrometry and instrumental {DELTA}V photometry of wide visual double stars. IV. Differential measurements of northern pairs.

Sinachopoulos, D.; van Dessel, E.; Nakos, T.

We present relative positions and instrumental visual magnitude differences ({DELTA}V) of 101 northern wide double star components. The mean accuracy of the magnitude differences is 0.01 magnitudes, of the angular separation 0.04 arcseconds, and of position angle 0.13 degrees. Most of the programme pairs are targets of the HIPPARCOS mission and th…

Photographic observations of visual double stars.

Jasinta, D. M. D.; Raharto, M.; Soegiartini, E.

We present the results of photographic observations of 399 visual double stars of the Hipparcos Input Catalogue (HIC), observed in the years 1980 and 1990-1991 with the 60-cm double-refractor of the Bosscha Observatory at Lembang, Java.

VRI photometry of wide double stars with A- type primaries.

Cuypers, J.; Lampens, P.; Sinachopoulos, D. +2 more

We are presenting VRI photometry of 93 wide visual double stars having late B- or A- type primaries, taken from the Annex of Double and Multiple Stars of the HIPPARCOS Input Catalogue. Spectral types have been estimated for most of the primaries and for the majority of the secondaries. 40% of them probably have common origin components, for which …
