Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. IV. The Large Magellanic Cloud: , Fe-peak, Light, and Heavy Elements
J. E. Colucci, R. A. Bernstein, S. A. Cameron +1
We present detailed chemical abundances in 8 clusters in the Large Magellanic Cloud (LMC). We measure abundances of 22 elements for clusters spanning a range in age of 0.05 to 12 G…
RR Lyrae Stars, Metal-Poor Stars, and the Galaxy
Andrew McWilliam
This online book contains the proceedings of a meeting on "RR Lyrae Stars, Metal-Poor Stars, and the Galaxy" held at the Carnegie Observatories, Pasadena, California, in January 20…
A differential chemical element analysis of the metal poor Globular Cluster NGC 6397
Andreas Koch, Andrew McWilliam
We present chemical abundances in three red giants and two turn-off stars in the metal poor Galactic globular cluster (GC) NGC 6397 based on spectroscopy obtained with the MIKE hig…
A Status Report on the 0Z Project
Judith G. Cohen, Norbert Christlieb, Andrew McWilliam +2
We present an update on the status of the 0Z Survey, an effort to datamine the Hamburg/ESO Survey to find and study in detail a large sample of extremely metal-poor Galactic halo f…
Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. III. The Large Magellanic Cloud: Fe and Ages
J. E. Colucci, R. A. Bernstein, S. A. Cameron +1
In this paper we refine our method for the abundance analysis of high resolution spectroscopy of the integrated light of unresolved globular clusters (GCs). This method was previou…
Alpha Enhancement and the Metallicity Distribution Function of Plaut's Window
Christian I. Johnson, R. Michael Rich, Jon P. Fulbright +2
We present Fe, Si, and Ca abundances for 61 giants in Plaut's Window (l=-1,b=-8.5) and Fe abundances for an additional 31 giants in a second, nearby field (l=0,b=-8) derived from h…
