Outer versus inner halo globular clusters: NGC 7492 abundances. Cohen J.G., Melendez J. <Astron. J., 129, 1607-1615 (2005)> =2005AJ....129.1607C
ADC_Keywords: Clusters, globular ; Equivalent widths ; Stars, giant Keywords: Galaxy: halo - globular clusters: general - globular clusters: individual (NGC 7492) - stars: abundances Abstract: We have carried out a detailed abundance analysis for 21 elements in a sample of four RGB stars in the outer halo globular cluster NGC 7492 (RGC 25kpc); we find [Fe/H]=-1.82dex inferred from Fe I lines (-1.79 from Fe II) using high-dispersion (R=λ/Δλ=35,000) spectra obtained with HIRES at the Keck Observatory.
