J/A+A/354/169       Metal-poor field stars abundances        (Gratton+, 2000)

Mixing along the red giant branch in metal-poor field stars Gratton R.G., Sneden C., Carretta E., Bragaglia A. <Astron. Astrophys. 354, 169 (2000)> =2000A&A...354..169G
ADC_Keywords: Stars, metal-deficient ; Abundances, peculiar ; Stars, population II ; Stars, giant Keywords: stars: Hertzsprung-Russel (HR) and C-M diagrams - stars: evolution - stars: Population II - Galaxy: globular clusters: general Abstract: We have determined Li, C, N, O, Na, and Fe abundances, and 12C/13C isotopic ratios for a sample of 62 field metal-poor stars in the metallicity range -2≤[Fe/H]≤-1. Stars were selected in order to have accurate luminosity estimates from the literature, so that evolutionary phases could be clearly determined for each star. We further enlarged this dataset by adding 43 more stars having accurate abundances for some of these elements and similarly well defined luminosities from the literature. File Summary:
