Preparing the COROT Space Mission: New Variable Stars in the Galactic Anticenter Direction
The activities related to the preparation of the asteroseismic,photometric space mission COROT are described. Photoelectricobservations, wide-field CCD photometry, uvbyβ calibrations, andfurther time series have been obtained at different observatories andtelescopes. They have been planned to complete the COROT program in thedirection of the Galactic anticenter. In addition to suitableasteroseismic targets covering the different evolutionary stages betweenzero-age main sequence and terminal-age main sequence, we discoveredseveral other variable stars, both pulsating and geometric. We comparedresults on the incidence of variability in the Galactic center andanticenter directions. Physical parameters have been obtained, andevolutionary tracks fitting them have been calculated. The peculiaritiesof some individual stars are pointed out.Based on observations collected at the San Pedro Martír, SierraNevada, Teide, La Silla, Haute-Provence, and Roque de Los Muchachos(Telescopio Nazionale Galileo and Mercator telescopes) observatories.

Radial velocities. Measurements of 2800 B2-F5 stars for HIPPARCOS
Radial velocities have been determined for a sample of 2930 B2-F5 stars,95% observed by the Hipparcos satellite in the north hemisphere and 80%without reliable radial velocity up to now. Observations were obtainedat the Observatoire de Haute Provence with a dispersion of 80Ä,mm(-1) with the aim of studying stellar and galactic dynamics.Radial velocities have been measured by correlation with templates ofthe same spectral class. The mean obtained precision is 3.0 km s(-1)with three observations. A new MK spectral classification is estimatedfor all stars. Based on observations made at the Haute ProvenceObservatory, France and on data from The Hipparcos Catalogue, ESA.Tables 4, 5 and 6 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr or viahttp://cdsweb.u-strasbg.fr/Abstract.htm
