The Bizarre Chemical Inventory of NGC 2419, An Extreme Outer Halo Globular Cluster
Judith G. Cohen, Evan N. Kirby
We present new Keck/HIRES observations of six red giants in the globular cluster NGC 2419. Although the cluster is among the most distant and most luminous in the Milky Way, it was…
The Peculiar Chemical Inventory of NGC 2419 -- An Extreme Outer Halo "Globular Cluster"
Judith Cohen, Wenjin Huang, Evan Kirby
NGC 2419 is a massive outer halo Galactic globular cluster whose stars have previously been shown to have somewhat peculiar abundance patterns. We have observed seven luminous gian…
A Puzzle Involving Galactic Bulge Microlensing Events
Judith G. Cohen, Andrew Gould, Ian B. Thompson +7
We study a sample of 16 microlensed Galactic bulge main sequence turnoff region stars for which high dispersion spectra have been obtained with detailed abundance analyses. We demo…
The Chemical Evolution of the Draco Dwarf Spheroidal Galaxy
Judith G. Cohen, Wenjin Huang
We present an abundance analysis based on high resolution spectra of 8 stars selected to span the full range in metallicity in the Draco dwarf spheroidal galaxy. We find [Fe/H] for…
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. Detailed abundance analysis of OGLE-2008-BLG-209S
T. Bensby, J. A. Johnson, J. Cohen +7
AIMS. Our aims are twofold. First we aim to evaluate the robustness and accuracy of stellar parameters and detailed elemental abundances that can be derived from high-resolution sp…
