High-Resolution Chemical Abundances of the Nyx Stream
Shuyu Wang, Lina Necib, Alexander P. Ji +5
Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk but with an unknown origin. Nyx could be the remnant of a disrupted dwarf gal…
Robust Clustering of the Local Milky Way Stellar Kinematic Substructures with Gaia eDR3
Xiaowei Ou, Lina Necib, Anna Frebel
We apply the clustering algorithm HDBSCAN on the Gaia early third data release astrometry combined with the Gaia second data release radial velocity measurements of almost 5.5 mill…
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…
