    • APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge 

      Fernández-Trincado, José Gregorio; Alves-Brito, Alan; Vieira, Katherine (2021) [Artigo de periódico]
      The central (‘bulge’) region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen (12C 14N). Some of these objects, which are also ...

    • The enigmatic globular cluster UKS 1 obscured by the bulge : H-band discovery of nitrogen-enhanced stars
