Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. II. Ages, metallicities, detailed elemental abundances, and connections to the Galactic thick disc
T. Bensby, S. Feltzing, J. A. Johnson +13
The Bulge is the least understood major stellar population of the Milky Way. Most of what we know about the formation and evolution of the Bulge comes from bright giant stars. The…

SEGUE: A Spectroscopic Survey of 240,000 stars with g=14-20
II SEGUE Collaboration, Brian Yanny, Constance Rockosi +2
The SEGUE survey obtained 240,000 moderate resolution (R = 1800) spectra from 3900 - 9000 Angstroms of fainter Milky Way stars (14.0 < g < 20.3) of a wide variety of spectral types…

Chemical abundances of 451 stars from the HARPS GTO planet search program: Thin disc, thick disc, and planets
V. Neves, N. C. Santos, S. G. Sousa +2
We present a uniform study of the chemical abundances of 12 elements (Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Na, Mg, and Al) derived from the spectra of 451 stars observed as part of o…
