    • The COMBS Survey -- III. The Chemodynamical Origins of Metal-Poor Bulge Stars 

      Lucey, Madeline; Hawkins, Keith; Ness, Melissa; Nelson, Tyler; Debattista, Victor P.; Luna, Alice; Bensby, Thomas; Freeman, Kenneth C.; Kobayashi, Chiaki (2022-01-01)
      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 important in light of cosmological simulations, ...

    • The COMBS survey I : Chemical Origins of Metal-Poor Stars in the Galactic Bulge 

      Lucey, Madeline; Hawkins, Keith; Ness, Melissa; Asplund, Martin; Bensby, Thomas; Casagrande, Luca; Feltzing, Sofia; Freeman, Kenneth C.; Kobayashi, Chiaki; Marino, Anna F. (2019-09-01)
      Chemistry and kinematic studies can determine the origins of stellar population across the Milky Way. The metallicity distribution function of the bulge indicates that it comprises multiple populations, the more metal-poor ...

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

      Lucey, Madeline; Hawkins, Keith; Ness, Melissa; Debattista, Victor P.; Luna, Alice; Asplund, Martin; Bensby, Thomas; Casagrande, Luca; Feltzing, Sofia; Freeman, Kenneth C.; Kobayashi, Chiaki; Marino, Anna F. (2021-03-01)
      The metal-poor stars in the bulge are important relics of the Milky Way's formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In order to determine if they are truly ancient ...
