Chemo-Dynamically Tagged Groups of CEMP Stars in the Halo of the Milky Way. I. Untangling the Origins of CEMP- and CEMP-no Stars
Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco +7
We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies. Dynamical parameters for t…
The chemical abundance pattern of the extremely metal-poor thin disk star 2MASS J1808-5104 and its origins
Mohammad K. Mardini, Anna Frebel, Rana Ezzeddine +6
We present a high-resolution (), high signal-to-noise () Magellan/MIKE spectrum of the bright extremely metal-poor star 2MASS~J18085104. We find [Fe/H] = $…
Possibilities and Limitations of Kinematically Identifying Stars from Accreted Ultra-Faint Dwarf Galaxies
Kaley Brauer, Hillary Diane Andales, Alexander P. Ji +4
The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight int…
The Atari Disk, a Metal-Poor Stellar Population in the Disk System of the Milky Way
Mohammad K. Mardini, Anna Frebel, Anirudh Chiti +3
We have developed a chemo-dynamical approach to assign 36,010 metal-poor SkyMapper stars to various Galactic stellar populations. Using two independent techniques (velocity and act…
Detailed chemical abundances of stars in the outskirts of the Tucana II ultra-faint dwarf galaxy
Anirudh Chiti, Anna Frebel, Alexander P. Ji +6
We present chemical abundances and velocities of five stars between 0.3 kpc to 1.1 kpc from the center of the Tucana II ultra-faint dwarf galaxy (UFD) from high-resolution Magellan…
