    • 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 ...
    • The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds 
      Nidever, David L.; Hasselquist, Sten; Hayes, Christian R.; Hawkins, Keith; Povick, Joshua; Majewski, Steven R.; Smith, Verne V.; Anguiano, Borja; Stringfellow, Guy S.; Sobeck, Jennifer S.; Cunha, Katia; Beers, Timothy C.; Bestenlehner, Joachim M.; Cohen, Roger; Garcia-Hernandez, D. A.; Jönsson, Henrik; Nitschelm, Christian; Shetrone, Matthew; Lacerna, Ivan; Allende Prieto, Carlos; Beaton, Rachael L.; Dell’Agli, Flavia; Fernández Trincado, José G.; Feuillet, Diane; Gallart, Carme; Hearty, Fred R.; Holtzman, Jon; Manchado, Arturo; Muñoz Vidal, Ricardo R.; O’Connell, Robert; Rosado, Margarita (IOP Publishing, 2020)
      We report the first APOGEE metallicities and alpha-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic Clouds, the largest Milky Way (MW) dwarf ...
    • TOI-150: A Transiting Hot Jupiter in the TESS Southern CVZ 
      Cañas, Caleb I.; Stefansson, Gudmundur; Monson, Andrew J.; Teske, Johanna K.; Bender, Chad F.; Mahadevan, Suvrath; Aerts, Conny; Beaton, Rachael L.; Butler, R. Paul; Covey, Kevin R.; Crane, Jeffrey D.; De Lee, Nathan; Díaz, Matías R.; Fleming, Scott W.; García Hernández, D. A.; Hearty, Fred R.; Kollmeier, Juna A.; Majewski, Steven R.; Nitschelm, Christian; Schneider, Donald P.; Shectman, Stephen A.; Stassun, Keivan G.; Tkachenko, Andrew; Wang, Sharon X.; Wang, Songhu; Wilson, John C.; Wilson, Robert F. (IOP Publishing, 2019)
      We report the detection of a hot Jupiter (M-p = 1.75(-0.17)(+0.14) M-J, R-p = 1.38 +/- 0.04R(J)) orbiting a middle-aged star (log g = 4.152(-0.043)(+0.030)) in the Transiting Exoplanet Survey Satellite (TESS) southern ...
