Elemental Abundance Survey of The Galactic Thick Disk

Bacham E. Reddy, David L. Lambert, Carlos Allende Prieto

[Abridged abstract] We have performed an abundance analysis for 176 F- and G- dwarfs of the Galactic thick disk component. Using accurate radial velocities combined with $Hipparcos…

Testing Rotational Mixing Predictions with New Boron Abundances in Main Sequence B-type Stars

J. T. Mendel, K. A. Venn, C. R. Proffitt +2

(Abridged) New boron abundances for seven main-sequence B-type stars are determined from HST STIS spectroscopy around the BIII 2066A line. Boron abundances provide a unique and cri…

Rubidium and lead abundances in giant stars of the globular clusters M 13 and NGC 6752

David Yong, Wako Aoki, David L. Lambert +1

We present measurements of the neutron-capture elements Rb and Pb in five giant stars of the globular cluster NGC 6752 and Pb measurements in four giants of the globular cluster M…

Mg isotope ratios in giant stars of the globular clusters M 13 and M 71

David Yong, Wako Aoki, David L. Lambert

We present Mg isotope ratios in 4 red giants of the globular cluster M 13 and 1 red giant of the globular cluster M 71 based on spectra obtained with HDS on the Subaru Telescope. W…

On the Origin of Sulfur

Nils Ryde, David L. Lambert

We present our work on the halo evolution of sulfur, based on observations of the S I lines around 9220 A for ten stars for which the S abundance was obtained previously from much…

Oxygen in Galactic Disk Stars: non-LTE abundances from the 777 nm O I triplet

I. Ramirez, C. Allende Prieto, D. L. Lambert

Oxygen abundances for a large sample of dwarf and giant stars kinematically selected to be part of the Galactic thin and thick disks have been determined from a non-LTE analysis of…
