J/ApJS/169/430 Atmospheric parameters of 1907 metal-rich stars (Robinson+, 2007)

The N2K consortium. VII. Atmospheric parameters of 1907 metal-rich stars: finding planet-search targets. Robinson S.E., Ammons S.M., Kretke K.A., Strader J., Wertheimer J.G., Fischer D.A., Laughlin G. <Astrophys. J. Suppl. Ser., 169, 430-438 (2007)> =2007ApJS..169..430R
ADC_Keywords: Stars, late-type ; Abundances ; Stars, nearby Keywords: methods: statistical ; planetary systems ; stars: abundances Abstract: 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, Teff≤6000K, and have a 10% or greater probability of hosting planets based on their metallicities. This catalog contains measurements of [Fe/H] (sigma[Fe/H]=0.07dex), Teff(sigma_Teff=82K), and logg (sigmalogg=0.13dex). Atmospheric parameters are derived from Lick index measurements, as described in Robinson et al. (2006, Cat. J/ApJ/637/1102). Lick indices are measured from spectra obtained with the GCAM spectrograph on the 2.1m telescope at KPNO. File Summary:

Note (1): 'b' means that the atmospheric parameter is out of tested range of Lick Indices calibration: 4100K<Teff<6400K, -0.95dex<[Fe/H]<0.5dex, 4.0dex<log(g)<5.1dex. Note (2): '*' means that the star is known to be a member of a binary or multiple system. Multiplicity information from SIMBAD database. Note (3): '*' means that a possible companion star was observed on the 2.1m telescope slit camera. Slit width 1.3", slit length 5.2".
