We present the results of an abundance analysis for a sample of stars with –4 < [ Fe/H ] < − 2. The data were obtained with the HIRES spectrograph at Keck Observatory. The set includes 28 stars, with effective temperature ranging from 4800 to 6600 K. For 13 stars with [ Fe/H ] < − 2.6, including nine with [ Fe/H ] < − 3.0 and one with [ Fe/H ] = − 4.0, these are the first reported detailed abundances. For the most metal-poor star in our sample, CS 30336–049, we measure an abundance pattern that… 

Chemical Abundances of Outer Halo Stars in the Milky Way

We present the chemical abundances of 57 metal-poor ([Fe=H] 5 kpc above and below the Galactic plane. High-resolution (R � 50000–55000), high signal-to-noise (S=N > 100) spectra for the sample stars

Carbon Abundances of Metal-Poor Stars Determined from the C I 1.068–1.069 μm Lines

A non-LTE analysis of C I lines at 1.068-1.069 micron was carried out for selected 46 halo/disk stars covering a wide metallicity range (-3.7 <[Fe/H]< +0.3), based on the spectral data collected with

Detailed abundances of 15 stars in the metal-poor globular cluster NGC 4833

We have observed 15 red giant stars in the relatively massive, metal-poor globular cluster NGC 4833 using the Magellan Inamori Kyocera Echelle spectrograph at Magellan. We calculate stellar

A UNIQUE STAR IN THE OUTER HALO OF THE MILKY WAY

As part of a program to measure abundance ratios in stars beyond 15 kpc from the Galactic center, we have discovered a metal-poor star in the outer halo with a unique chemical signature. We

With a sample of 22 metal-poor stars, we demonstrate that the heavy-element abundance pattern (Z ≥ 56) is the same as the r-process contributions to the solar nebula. This bolsters the results of
