    • Abundance ratios of red giants in low-mass ultra-faint dwarf spheroidal galaxies 

      François, P.; Monaco, L.; Bonifacio, P.; Moni Bidin, C.; Geisler, D. (EDP SCIENCES, 2016-04)
      Context. Low-mass dwarf spheroidal galaxies are key objects for our understanding of the chemical evolution of the pristine Universe and the Local Group of galaxies. Abundance ratios in stars of these objects can be used ...
    • The central spheroids of Milky Way mass-sized galaxies 

      Tissera, P.B.; Machado, R.E.G.; Carollo, D.; Minniti, D.; Beers, T.C.; Zoccali, M.; Meza, A. (Oxford University Press, 2018-01)
      We study the properties of the central spheroids located within 10 kpc of the centre of mass of MilkyWay mass-sized galaxies simulated in a cosmological context. The simulated central regions are dominated by stars older ...
