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

      Fishlock, C. K.; Yong, D.; Karakas, A. I.; Alves-Brito, A.; Melendez, J.; Nissen, P. E.; Kobayashi, C.; Casey, A. R. (2017-05-01)
      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 ...
