Galaxy Mergers: A Search for Chemical Signatures
Inese I. Ivans, Bruce Carney, Luisa de Almeida +1
We have gathered high resolution echelle spectra for more than two dozen high-velocity metal-poor field stars, including BD+80 245, a star previously known to have extremely low [a…
Getting the Red Out: A Stellar Approach to Determining Spatial Variations of Interstellar Dust
I. I. Ivans, C. Sneden, R. P. Kraft +4
By employing two different spectroscopic techniques we have mapped out the variable ISM dust extinction endemic to globular cluster M4. We derive an average E(B-V) reddening of 0.3…
Do AGB Stars Differ Chemically from RGB Stars in Globular Clusters?
Christopher Sneden, Inese I. Ivans, Robert P. Kraft
Recent improvements in globular cluster colour-magnitude diagrams, coupled with an increase in large-sample spectroscopic abundance studies of cluster giants, finally allow some at…
