The COMBS Survey -- II. Distinguishing the Metal-Poor Bulge from the Halo Interlopers

no code implementations • 8 Sep 2020 • Madeline Lucey, Keith Hawkins, Melissa Ness, Victor P. Debattista, Alice Luna, Martin Asplund, Thomas Bensby, Luca Casagrande, Sofia Feltzing, Kenneth C. Freeman, Chiaki Kobayashi, Anna F. Marino

Currently, it is unclear if the metal-poor stars in the bulge ([Fe/H] < -1 dex) are merely halo interlopers, a unique accreted population, part of the boxy/peanut-shaped (B/P) bulge or a classical bulge population.
