(2023) [Artigo de periódico]
      Context. The recent and exquisite astrometric, photometric, and radial velocity measurements of the Gaia mission resulted in a substantial advancement of the determination of the orbits for old star clusters, including the ...

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

      Fernández-Trincado, José Gregorio; Minniti, Dante; Beers, Timothy C.; Villanova , Sandro; Geisler, Doug; Souza, Stefano O.; Smith, Leigh C.; Placco, Vinicius M.; Vieira, Katherine; Pérez Villegas, Maria de Los Angeles; Barbuy, Beatriz; Alves-Brito, Alan; Bidin, Christian Moni; Alonso Garcia, Javier; Tang, Baitian; Palma, Tali (2020) [Artigo de periódico]
      The presence of nitrogen-enriched stars in globular clusters provides key evidence for multiple stellar populations (MPs), as has been demonstrated with globular cluster spectroscopic data towards the bulge, disk, and halo. ...
