      We report an analysis of the metal-rich tail ([Fe/H]>−0.75) of stars located at distances fromthe Galactic plane up to|z|∼10 kpc, observed by the Apache Point Observatory GalacticEvolution Experiment (APOGEE). We examine ...

    • The Milky Way bar and bulge revealed by APOGEE and Gaia EDR3 

      Queiroz, Anna Bárbara de Andrade; Santiago, Basilio Xavier; Zasowski, G. (2021) [Journal article]
      We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3. Our inner Galactic sample has more than 26 500 stars within |XGal| < 5 kpc, |YGal| < 3.5 kpc, |ZGal| < 1 kpc, and we also carry out ...
