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 the N2K low-resolution spectroscopic survey, designed to identify metal-rich FGK dwarfs likely to harbor detectable planets. Of these stars, 284 are in the ideal temperature range for planet searches, T-eff <= 6000 K, and have a 10% or greater probability of hosting planets based on their metallicities. The stars in the low-resolution spectroscopic survey should eventually yield >60 new planets, including 8- hot Jupiters. Short-period planets have already been discovered orbiting the survey targets HIP 14810 and HD 149143.
