J/A+A/356/238  Atmospheric parameters in metal-poor stars. III. (Carretta+ 2000)

Abundances of light elements in metal-poor stars. III. Data analysis and results Carretta E., Gratton R.G., Sneden C. <Astron. Astrophys. 356, 238 (2000)> =2000A&A...356..238C
ADC_Keywords: Stars, metal-deficient ; Abundances Keywords: stars: abundances - nuclear reactions, nucleosynthesis, abundances - Galaxy : evolution Abstract: We present the results of the analysis of an extensive set of new and literature high quality data concerning Fe, C, N, O, Na, and Mg. This analysis exploited the Teff scale determined in Gratton et al. (1996, Cat. J/A+A/314/191), and the non-LTE abundance corrections computed in Gratton et al. (1999, Cat. J/A+A/350/955). Results obtained with various abundance indices are discussed and compared. File Summary:
