The N2K Consortium. VII. Atmospheric Parameters of 1907 Metal-rich Stars: Finding Planet-Search Targets
We report high-precision atmospheric parameters for 1907 stars in theN2K low-resolution spectroscopic survey, designed to identify metal-richFGK dwarfs likely to harbor detectable planets. Of these stars, 284 arein the ideal temperature range for planet searches,Teff<=6000 K, and have a 10% or greater probability ofhosting planets based on their metallicities. The stars in thelow-resolution spectroscopic survey should eventually yield >60 newplanets, including 8-9 hot Jupiters. Short-period planets have alreadybeen discovered orbiting the survey targets HIP 14810 and HD 149143.

Multicolor Observations of a Planetary Transit of HD 209458
We present BVRIZ photometric observations of HD 209458 during thetransit by its planetary companion on UT 1999 November 15 with theUniversity of Hawaii 0.6 and 2.2 m telescopes and the High AltitudeObservatory STARE telescope. The detailed shape of the transit curve ispredicted to vary with color primarily as a result of thecolor-dependent limb darkening of the star but potentially due as wellto the effect of color-dependent opacity in the planetary atmosphere. Wemodel the light curves and present refined values for the transit timingand orbital period, useful for planning future observations of theplanetary transit. We also derive significantly improved measurements ofthe planetary radius, Rp=1.55+/-0.10 RJup, stellarradius, Rs=1.27+/-0.05 Rsolar, and orbitalinclination, i=85.9d+/-0.5d. The derived planetary radius favorsevolutionary models in which the planet has a low albedo.

Mesures de vitesses radiales. VIII. Accompagnement AU sol DU programme d'observation DU satellite HIPPARCOS
We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.
