Chemical Abundance Analysis of the Extremely Metal-Poor Star HE 1300+0157
Anna Frebel, John E. Norris, Wako Aoki +5
We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H]=-3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched…

Chemical Homogeneity in Collinder 261 and Implications for Chemical Tagging
G. M. De Silva, K. C. Freeman, M. Asplund +3
This paper presents abundances for 12 red giants of the old open cluster Collinder 261 based on spectra from VLT/UVES. Abundances were derived for Na, Mg, Si, Ca, Mn, Fe, Ni, Zr an…

Spectroscopy of Be stars in the Small Magellanic Cloud cluster NGC 330
Stefan C. Keller, Michael S. Bessell
The presence of an anomalously large population of Be stars in the young cluster NGC 330 in the SMC has been noted by Feast (1972), Bessell & Wood (1993), Grebel (1996) and most re…
