A catalogue of Paschen-line profiles in standard stars
Wenjin Huang, George Wallerstein, Myra Stone
We have assembled an atlas of line profiles of the Paschen Delta line at 10,049 angstroms for the use of stellar modelling. For a few stars we have substituted the Paschen Gamma li…
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…
Metal Abundance Calibration of the Ca II Triplet Lines in RR Lyrae Stars
George Wallerstein, Thomas Gomez, Wenjin Huang
The GAIA satellite is likely to observe thousands of RR Lyrae stars within a small spectral window, between 8470A and 8750A, at a resolution of 11,500. In order to derive the metal…
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 Stellar Rotation Census of B Stars: from ZAMS to TAMS
Wenjin Huang, Douglas R. Gies, M. Virginia McSwain
Two recent observing campaigns provide us with moderate dispersion spectra of more than 230 cluster and 370 field B stars. Combining them and the spectra of the B stars from our pr…
The Chemical Evolution of the Ursa Minor Dwarf Spheroidal Galaxy
Judith G. Cohen, Wenjin Huang
We present an abundance analysis based on high resolution spectra of 10 stars selected to span the full range in metallicity in the Ursa Minor dwarf spheroidal galaxy. We find [Fe/…
