Abundances for metal-poor stars with accurate parallaxes. I. Basic data. Gratton R.G., Carretta E., Claudi R., Lucatello S., Barbieri M. <Astron. Astrophys. 404, 187 (2003)> =2003A&A...404..187G
ADC_Keywords: Stars, metal-deficient ; Stars, population II ; Equivalent widths Keywords: Stars: abundances - Star: evolution - Stars: Population II - Galaxy: globular clusters: general Abstract: We present element-to-element abundance ratios measured from high dispersion spectra for 150 field subdwarfs and early subgiants with accurate Hipparcos parallaxes (errors<20%). For 50 stars new spectra were obtained using the UVES on Kueyen (VLT UT2), the McDonald 2.7m telescope, and SARG at TNG. Additionally, literature equivalent widths were taken from the works by Nissen & Schuster (1997, Cat. J/A+A/326/751), Fullbright (2000AJ....120.1841F), and Prochaska et al. (2000AJ....120.2513P) to complement our data. The whole sample includes both thick disk and halo stars (and a few thin disk stars); most stars have metallicities in the range -2<[Fe/H]←0.6. We found our data, that of Nissen & Schuster, and that of Prochaska to be of comparable quality; results from Fulbright scatter a bit more, but they are still of very good quality and are extremely useful due to the large size of his sample. The results of the present analysis will be used in forthcoming papers to discuss the chemical properties of the dissipational collapse and accretion components of our Galaxy. Description: Equivalent widths for 50 metal poor stars measured from high resolution spectra obtained at the ESO VLT2 telescope (UVES), McDonald 2.7m, and TNG telescopes (SARG spectrograph).
