    • Chemical abundances in bright giants of the globular cluster M62 (NGC 6266) 

      Yong, David; Alves-Brito, Alan; Da Costa, Gary Stewart; Alonso Garcia, Javier; Karakas, Amanda I.; Pignatari, Marco; Roederer, Ian U.; Aoki, Wako; Fishlock, Cherie K.; Grundahl, Frank; Norris, John E. (2014) [Artigo de periódico]
      With the exception of Terzan 5, all the Galactic globular clusters that possess significant metallicity spreads, such as ω Cen and M22, are preferentially the more luminous clusters with extended horizontal branches. Here ...

    • Sc and neutron-capture abundances in Galactic low- and high-α field halo stars 

      Fishlock, Cherie K.; Yong, David; Karakas, Amanda I.; Alves-Brito, Alan; Meléndez, Jorge; Nissen, Poul Erik; Kobayashi, Chiaki; Casey, Andrew Raithby (2017) [Artigo de periódico]
      We determine relative abundance ratios for the neutron-capture elements Zr, La, Ce, Nd and Eu for a sample of 27 Galactic dwarf stars with −1.5 < [Fe/H] < −0.8. We also measure the iron-peak element Sc. These stars separate ...
