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…
Chemical Homogeneity in the Hyades
G. M. De Silva, C. Sneden, D. B. Paulson +4
We present an abundance analysis of the heavy elements Zr, Ba, La, Ce, and Nd for Hyades cluster F-K dwarfs based on high resolution, high S/N ratio spectra from Keck/HIRES. The de…
Galactic Winds
S. Veilleux, G. Cecil, J. Bland-Hawthorn
Galactic winds are the primary mechanism by which energy and metals are recycled in galaxies and are deposited into the intergalactic medium. New observations are revealing the ubi…
Science Programs for a 2 m-class Telescope at Dome C, Antarctica: PILOT, the Pathfinder for an International Large Optical Telescope
M. G. Burton, J. Lawrence, M. C. B. Ashley +24
The cold, dry and stable air above the summits of the Antarctic plateau provides the best ground-based observing conditions from optical to sub-mm wavelengths to be found on the Ea…
