Beginning of ReadMe : J/AJ/131/1766 Abundances and equivalent widths in NGC 2808 (Carretta, 2006) ================================================================================ Abundances in red giant stars of NGC 2808 and correlations between chemical anomalies and global parameters in globular clusters. Carretta E. <Astron. J., 131, 1766-1783 (2006)> =2006AJ....131.1766C ================================================================================ ADC_Keywords: Clusters, globular ; Stars, population II ; Abundances ; Equivalent widths Keywords: globular clusters: general - globular clusters: individual (NGC 2808) - stars: abundances - stars: evolution - stars: Population II Abstract: We present the abundance analysis of stars from the tip of the red giant branch (RGB) to below the RGB bump in the globular cluster NGC 2808 based on high-resolution echelle spectra. We derive abundances of Al, alpha-process elements (SiI, CaI, TiI, and TiII), and Fe-group elements (ScII, VI, CrI, CrII, MnI, CoI, and NiI). Apart from Mg being somewhat reduced, likely because it has been depleted at the expense of Al in the MgAl cycle, the other alpha-element ratios show the overabundance typical of halo stars of similar metallicity. Description: The program stars were observed during the FLAMES Science Verification program at the ESO Paranal Observatory on 2003 January 24-25. All the stars were observed with the fiber-fed red arm of the high-resolution Ultraviolet and Visual Echelle Spectrograph (UVES; R 47000, fibers of 1"; entrance aperture, grating centered at 5800AA with spectral coverage of about 2000AA).
