Cloud Structure and Physical Conditions in Star-forming Regions from Optical Observations. I. Data and Component Structure
K. Pan, S. R. Federman, K. Cunha +2
We present high-resolution optical spectra (at ~0.6--1.8 km s-1) of interstellar CN, CH, CH^+, \ion{Ca}{1}, \ion{K}{1}, and \ion{Ca}{2} absorption toward 29 lines of sight in three…
High-Resolution Infrared Spectroscopy of the Brown Dwarf Epsilon Indi Ba
Verne V. Smith, Takashi Tsuji, Kenneth H. Hinkle +6
We report on the analysis of high-resolution infrared spectra of the newly discovered brown dwarf Epsilon Indi Ba. This is the closest known brown dwarf to the solar system, with a…
Chemical Evolution in Omega Centauri
Verne V. Smith
The globular cluster Omega Centauri displays evidence of a complex star formation history and peculiar internal chemical evolution, setting it apart from essentially all other glob…
Fluorine Abundances in the Large Magellanic Cloud and Omega Centauri: Evidence for Neutrino Nucleosynthesis?
K. Cunha, V. V. Smith, D. L. Lambert +1
The behavior of fluorine with metallicity has not yet been probed in any stellar population. In this work, we present the first fluorine abundances measured outside of the Milky Wa…
A Comparison of Copper Abundances in Globular Cluster and Halo Field Giant Stars
Jennifer Simmerer, Christopher Sneden, Inese I. Ivans +3
We derive [Cu/Fe] for 117 giant stars in ten globular clusters (M3, M4, M5, M10, M13, M15, M71, NGC 7006, NCG 288, and NGC 362) and find that globular cluster Cu abundances appear…
