Identifying Sagittarius Stream Stars by Their APOGEE Chemical Abundance Signatures
Identifying Sagittarius Stream Stars by Their APOGEE Chemical Abundance Signatures
The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey provides precise chemical abundances of 18 chemical elements for $\sim$ 176,000 red giant stars distributed over much of the Milky Way Galaxy (MW), and includes observations of the core of the Sagittarius dwarf spheroidal galaxy (Sgr). The APOGEE chemical abundance …
