  • Abstract
    On the basis of a previous paper, we have determined the atmospheric parameters and the abundance of nine chemical elements for a sample of stars. we discuss the changes of the abundances with [FeH]. The mean [NaFe]∼- 0.01 dex is close to the solar abundance. Of the α elements Si and Ca possess almost the same abundance model, [TiFe] has a rather large scatter while all three tend to increase with decreasing [FeH]. The iron-peak elements, V, Cr and Ni have comparatively large scatters in their abundance. For all the sample stars, [CrFe] is over-abundant, and [MnFe] is under-abundant. The latter also increases with increasing metal abundances.
