The N2K consortium. V. Identifying very metal-rich stars with low-resolution spectra: finding planet-search targets. Robinson S.E., Strader J., Ammons S.M., Laughlin G., Fischer D. <Astrophys. J., 637, 1102-1112 (2006)> =2006ApJ...637.1102R
ADC_Keywords: Stars, nearby ; Spectroscopy ; Abundances Keywords: methods: statistical - planetary systems - stars: abundances Abstract: We present empirical calibrations that provide estimates of stellar metallicity, effective temperature, and surface gravity as a function of Lick IDS indices. These calibrations have been derived from a training set of 261 stars for which (1) high-precision measurements of [Fe/H], Teff, and log(g) have been made using spectral-synthesis analysis of HIRES spectra, and (2) Lick indices have also been measured. Description: The N2K consortium was created to identify the "next two thousand" metal-rich dwarf stars that would be suitable for radial-velocity planet searches. Our observations were taken at two telescopes, the Nickel 1m at Lick Observatory and the 2.1m at Kitt Peak National Observatory. The Nickel observations were taken during 2004 April 23-26 and 2004 July 13-15. The 2.1m observations were taken during 2004 August 27 - September 2 with the GoldCam spectrograph. File Summary:
