J/PASP/113/1365        Super-metal-rich stars       (Buzzoni+, 2001)

Lick spectral indices for super-metal-rich stars. Buzzoni A., Chavez M., Malagnini M.L., Morossi C. <Publ. Astron. Soc. Pac. 113, 1365 (2001)> =2001PASP..113.1365B
ADC_Keywords: Abundances, peculiar ; Abundances, [Fe/H] Abstract: We present Lick spectral indices for a complete sample of 139 candidate super-metal-rich stars of different luminosity classes (MK type from I to V). For 91 of these stars we were able to identify, in an accompanying paper, the fundamental atmosphere parameters. This confirms that at least 2/3 of the sample consists of stars with [Fe/H] in excess of +0.1 dex. Optical indices for both observations and fiducial synthetic spectra have been calibrated to the Lick system according to Worthey et al. (1994, Cat. J/ApJS/94/687) and include the FeI indices of Fe5015, Fe5270, and Fe5335 and the MgI and MgH indices of Mg2 and Mgb at 5180Å. The internal accuracy of the observations is found to be σ(Fe5015)=10.32Å, σ(Fe5270)=10.19Å, σ(Fe5335)=10.22Å, σ(Mg2)=10.004mag, and σ(Mgb)=10.19Å. This is about a factor of 2 better than the corresponding theoretical indices from the synthetic spectra, the latter being a consequence of the intrinsic limitations in the input physics, as discussed by Chavez et al. (1997, Cat. J/A+AS/126/267). File Summary:
