    • Chemical Composition of Young Stars in the Leading Arm of the Magellanic System 
      Zhang, Lan; Moni Bidin, Christian; Casetti-Dinescu, Dana I.; Méndez, Réne A.; Girard, Terrence M.; Korchagin, Vladimir I.; Vieira, Katherine; Van Altena, William F.; Zhao, Gang (IOP Publishing, 2017)
      Chemical abundances of eight O-and B-type stars are determined from high-resolution spectra obtained with the MIKE instrument on the Magellan. 6.5 m Clay telescope. The sample is selected from 42 candidates for membership ...
    • Metallicity and alpha-element abundance gradients along the Sagittarius Stream as seen by APOGEE 
      Hayes, Christian; Majewski, Steven; Hasselquist, Sten; Anguiano, Borja; Shetrone, Matthew; Law, David; Schiavon, Ricardo; Cunha, Katia; Smith, Verne; Beaton, Rachael; Price Whelan, Adrián; Allende Prieto, Carlos; Battaglia, Giuseppina; Bizyaev, Dimitry; Brownstein, Joel; Cohen, Roger; Frinchaboy, Peter; García Hernández, D. A.; Lacerna, Iván; Lane, Richard; Meszaros, Szabolcs; Moni Bidin, Christian; Muñoz Vidal, Ricardo; Nidever, David; Oravetz, Audrey; Oravetz, Daniel; Pan, Kaike; Román Lopes, Alexandre; Sobeck, Jennifer; Stringfellow, Guy (IOP, 2020)
      Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Observatory Galactic Evolution Experiment ...
    • 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 ...
