The Two Metallicity Groups Of The Globular Cluster M22: A Chemical Perspective

Marino, A. F.; Sneden, Christopher; Kraft, R. P.; Wallerstein, G.; Norris, J. E.; Da Costa, G.; Milone, A. P.; Ivans,, II; Gonzalez, G.; Fulbright, J. P.; Hilker, M.; Piotto, G.; Zoccali, M.; Stetson, P. B. (2011-08)

We present a detailed chemical composition analysis of 35 red giant stars in the globular cluster M22. High resolution spectra for this study were obtained at five observatories, and analyzed in a uniform manner. We have ...
