Abundance evolution of intermediate mass elements (C to Zn) in the Milky Way halo and disk

Goswami, A; Prantzos, N (European Southern Observatory, 2000-07)

We present a comprehensive study of the evolution of the abundances of intermediate mass elements, from C to Zn, in the Milky Way halo and in the local disk. We use a consistent model to describe the evolution of those two ...
A search for unrecognized carbon-enhanced metal-poor stars in the galaxy

Placco, V. M; Kennedy, C. R; Rossi, S; Beers, T. C; Lee, Y. S; Christlieb, N; Sivarani, T; Reimers, D; Wisotzki, L (Institute of Physics, 2010-03)

We have developed a new procedure to search for carbon-enhanced metal-poor (CEMP) stars from the Hamburg/ESO (HES) prism-survey plates. This method employs an extended line index for the CH G band, which we demonstrate to ...
Upper Limits on O VI Emission From Voyager Observations

Murthy, J; Henry, R. C; Shelton, R. L; Holberg, J. B (American Astronomical Society, 2001-08)

We have examined 426 Voyager fields distributed across the sky for O VI λλ1032, 1038 emission from the Galactic diffuse interstellar medium. No such emission was detected in any of our observed fields. Our most constraining ...
