The Active Chromospheres of Lithium-Rich Red Giant Stars
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +17
We have gathered near-infrared -band high resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their \species{He}{i} 1083…
The Chemical Composition of Extreme-Velocity Stars
Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman +5
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use t…
The detailed chemical abundance patterns of accreted halo stars from the optical to infrared
Andreia Carrillo, Keith Hawkins, Paula Jofré +3
Understanding the assembly of our Galaxy requires us to also characterize the systems that helped build it. In this work, we accomplish this by exploring the chemistry of accreted…
A GALAH View of the Chemical Homogeneity and Ages of Stellar Strings Identified in Gaia
Catherine Manea, Keith Hawkins, Zachary G. Maas
The advent of Gaia has led to the discovery of nearly 300 elongated stellar associations (called `strings') spanning hundreds of parsecs in length and mere tens of parsecs in width…
The COMBS Survey -- III. The Chemodynamical Origins of Metal-Poor Bulge Stars
Madeline Lucey, Keith Hawkins, Melissa Ness +6
The characteristics of the stellar populations in the Galactic Bulge inform and constrain the Milky Way's formation and evolution. The metal-poor population is particularly importa…
The Stars of the HETDEX Survey. I. Radial Velocities and Metal-Poor Stars from Low-Resolution Stellar Spectra
Keith Hawkins, Greg Zeimann, Chris Sneden +18
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is an unbiased, massively multiplexed spectroscopic survey, designed to measure the expansion history of the universe thr…
