In Pursuit of Galactic Archaeology: Astro2020 Science White Paper
Melissa Ness, Jonathan Bird, Jennifer Johnson +30
The next decade affords tremendous opportunity to achieve the goals of Galactic archaeology. That is, to reconstruct the evolutionary narrative of the Milky Way, based on the empir…
Binarity among CEMP-no stars: an indication of multiple formation pathways?
Anke Arentsen, Else Starkenburg, Matthew D. Shetrone +3
Carbon-enhanced metal-poor (CEMP) stars comprise a large percentage of stars at the lowest metallicities. The stars in the CEMP-no subcategory do not show any s-process enhancement…
Carbon-enhanced metal-poor stars in the SDSS-APOGEE database
Collin L. Kielty, Kim A. Venn, Nicholas B. Loewen +5
We identify six new CEMP stars ([C/Fe]>+0.7 and [Fe/H]< -1.8) and another seven likely candidates within the APOGEE database following Data Release 12. These stars have chemical co…
The chemistry of the most metal-rich damped Lyman systems at z II. Context with the Local Group
Trystyn A. M. Berg, Sara L. Ellison, J. Xavier Prochaska +2
Using our sample of the most metal-rich damped Lyman systems (DLAs) at z, and two literature compilations of chemical abundances in 341 DLAs and 2818 stars, we present a…
A Search for Boron in Damped Lyα Systems
Trystyn A. M. Berg, Sara L. Ellison, Kim A. Venn +1
We present the first systematic study of boron beyond the Local Group. This analysis is performed on a sample of 30 damped Lyα systems (DLAs) with strong metal-lines, which are exp…
The Resolved Structure and Dynamics of an Isolated Dwarf Galaxy: A VLT and Keck Spectroscopic Survey of WLM
Ryan Leaman, Kim A. Venn, Alyson M. Brooks +7
We present spectroscopic data for 180 red giant branch stars in the isolated dwarf irregular galaxy WLM. Observations of the Calcium II triplet lines in spectra of RGB stars coveri…
