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.

The distribution of G5-M stars in a region at the south galactic pole
A survey has been conducted of an 81-sq deg area at the south galacticpole (SGP) in order to study the late-type star distribution as afunction of distance from the galactic plane. Both spectral types andluminosity classes are obtained from objective-prism spectra, usingclassification criteria closely associated with the MK classificationsystem. The SGP data are compiled into a catalog of 2228 stars of typeG5 and later, to a limiting magnitude of V=13.5 mag. An analysis of thedensity distribution of both dwarfs and giants indicates that the numberof dwarfs, as a function of magnitude, appears inconsistent with theassumption of a uniform density distribution for these stars.
