A New Population of Old Stars
I. I. Ivans, C. Sneden, C. R. James +5
We report the results of a coherent study of three chemically anomalous metal-poor ([Fe/H] ~ -2) stars. These objects exhibit unusually low abundances of Mg, Si, Ca (alpha-elements…

A New Globular Cluster Metallicity Scale Based on the Abundance of FeII
R. P. Kraft, I. I. Ivans
When using Fe as a surrogate for ``metallicity'', the metallicity is best represented by the dominant species of Fe. Accordingly, we have derived a new globular cluster metallicity…
