英文摘要 | 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 [Fe/H]. The mean [Na/Fe]similar to-0.01 dex is close to the solar abundance. Of the alpha elements Si and Ca possess almost the same abundance model, [Ti/Fe] has a rather large scatter while all three tend to increase with decreasing [Fe/H]. The iron-peak elements V, Cr and Ni have comparatively large scatters in their abundance. For all the sample stars, [Cr/Fe] is over-abundant, and [Mn/Fe] is under-abundant. The latter also increases with increasing metal abundances. |
