Atmospheric parameters of 1907 metal-rich stars
Listed in IVOA Registry (Virtual Observatory)
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.
Description
Of these stars, 284 are in the ideal temperature range for planet searches, T_eff_<=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), T_eff_(sigma_Teff=82K), and logg (sigma_logg_=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.
