    • Stellar and planetary characterization of the ross 128 exoplanetary system from APOGEE spectra 
      Souto, Diogo; Unterborn, Cayman T.; Smith, Verne V.; Cunha, Katia; Teske, Johanna; Covey, Kevin; Rojas Ayala, Barbara; García Hernández, D. A.; Stassun, Keivan; Zamora, Olga; Masseron, Thomas; Johnson, J. A.; Majewski, Steven R.; Jonsson, Henrik; Gilhool, Steven; Blake, Cullen; Santana, Felipe (IOP Publishing, 2018-06-10)
      The first detailed chemical abundance analysis of the M-dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5-1.7 mu m), high-resolution (R similar to 22,500) spectra from the SDSS ...
    • The age-chemical abundance structure of the Galactic disc - II. alpha-dichotomy and thick disc formation 
      Lian, Jianhui; Thomas, Daniel; Maraston, Claudia; Beers, Timothy C.; Moni Bidin, Christian; Fernández Trincado, José G.; Garcia-Hernandez, D. A.; Lane, Richard R.; Muñoz Vidal, Ricardo; Nitschelm, Christian; Roman Lopes, Alexandre; Zamora, Olga (Oxford University Press, 2020)
      We extend our previous work on the age-chemical abundance structure of the Galactic outer disc to the inner disc (4 < r < 8 kpc) based on the SDSS/APOGEE survey. Different from the outer disc, the inner disc stars exhibit ...
    • Two groups of red giants with distinct chemical abundances in the bulge globular cluster NGC 6553 through ... 
      Tang, Baitian; Cohen, Roger E.; Geisler, Doug; Schiavon, Ricardo P.; Majewski, Steven R.; Villanova, Sandro; Carrera, Ricardo; Zamora, Olga; García Hernández, D. A.; Shetrone, Matthew; Frinchaboy, Peter; Meza, Andrés; Fernández Trincado, J. G.; Muñoz Vidal, Ricardo Rodrigo; Lin, Chien-Cheng; Lane, Richard R.; Nitschelm, Christian; Pan, Kaike; Bizyaev, Dmitry; Oravetz, Daniel; Simmons, Audrey (Oxford University, 2017)
      Multiple populations revealed in globular clusters (GCs) are important windows to the forma-tion and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are anindispensable part of this picture, ...
