Constraints on the Formation of the Galactic Bulge from Na, Al, and Heavy Element Abundances in Plaut's Field
Christian I. Johnson, R. Michael Rich, Chiaki Kobayashi +1
We report chemical abundances of Na, Al, Zr, La, Nd, and Eu for 39 red giant branch (RGB) stars and 23 potential inner disk red clump stars located in Plaut-s low extinction window…
The two metallicity groups of the globular cluster M22: a chemical perspective
A. F. Marino, C. Sneden, R. P. Kraft +11
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, a…
A Large Sample Study of Red Giants in the Globular Cluster Omega Centauri (NGC 5139)
Christian I. Johnson, Catherine A. Pilachowski, R. Michael Rich +1
We present abundances of several light, alpha, Fe-peak, and neutron-capture elements for 66 red giant branch (RGB) stars in the Galactic globular cluster Omega Centauri. Our observ…
