• Improved yttrium and zirconium abundances in metal-poor stars 

      Violante, Renata (2012-01)
      We present new abundances of the lighter n-capture elements, Yttrium (Z=30) and Zirconium (Z=40) in the very metal-poor, r-process rich stars BD+17 3248 and HD 221170. Very accurate abundances were obtained by use of the ...
