Light-Element Abundance Variations at Low Metallicity: the Globular Cluster NGC 5466
Matthew Shetrone, Sarah L. Martell, Rachel Wilkerson +4
We present low-resolution (R~850) spectra for 67 asymptotic giant branch (AGB), horizontal branch and red giant branch (RGB) stars in the low-metallicity globular cluster NGC 5466,…

Light-element Abundance Variations in the Milky Way Halo
Sarah L. Martell, Eva K. Grebel
We present evidence for the contribution of high-mass globular clusters to the stellar halo of the Galaxy. Using SDSS-II/SEGUE spectra of over 1900 G- and K-type halo giants, we id…
