Carbon Abundances of Three Carbon-Enhanced Metal-Poor Stars from High-Resolution Gemini-S/bHROS Spectra of the 8727A [C I] Line
S. C. Schuler, S. J. Margheim, T. Sivarani +4
We present the results from an analysis of the 8727ang forbidden [C I] line in high-resolution Gemini-S/bHROS spectra of three CEMP stars. We find the [C/Fe] ratios based on the [C…
Fluorine in a Carbon-Enhanced Metal-Poor Star
S. C. Schuler, K. Cunha, V. V. Smith +3
The fluorine abundance of the Carbon-Enhanced Metal-Poor (CEMP) star HE 1305+0132 has been derived by analysis of the molecular HF (1-0) R9 line at 2.3357 microns in a high-resolut…
Hyades Oxygen Abundances from the Lambda 6300 [O I] Line: The Giant-Dwarf Discrepancy Revisited
S. C. Schuler, A. P. Hatzes, J. R. King +2
We present the results of our abundance analysis of Fe, Ni, and O in high S/N, high-resolution VLT/UVES and McDonald/2dcoude spectra of nine dwarfs and three giants in the Hyades o…
Oxygen from the Lambda 7774 High-Excitation Triplet in Open Cluster Dwarfs: Hyades
Simon C. Schuler, Jeremy R. King, Donald M. Terndrup +3
Oxygen abundances have been derived from the near-IR, high-excitation Lambda 7774 O I triplet in high-resolution, high signal-to-noise spectra of 45 Hyades dwarfs using standard on…
High-Resolution Spectroscopy of the Planetary Host HD 13189: Highly-Evolved and Metal-Poor
Simon C. Schuler, James H. Kim, Michael C. Tinker +3
We report on the abundances of 13 elements in the planetary host HD 13189, a massive giant star. Abundances are found to be sub-solar, with [Fe/H] = -0.58 +/- 0.04$; HD 13189 is on…
Keck/HIRES Spectroscopy of Four Candidate Solar Twins
Jeremy R. King, Ann M. Boesgaard, Simon C. Schuler
We use high S/N, high-resolution Keck/HIRES spectroscopy of 4 solar twin candidates (HIP 71813, 76114, 77718, 78399) from our Hipparcos-based CaII H & K survey to carry out paramet…
High-Resolution Spectroscopy of Ursa Major Moving Group Stars
Jeremy R. King, Simon C. Schuler
We use new and extant literature spectroscopy to address abundances and membership for UMa moving group stars. We first compare the UMa, Coma, and Hyades H-R diagrams via a homogen…
