Abstract

We present high-resolution chemical abundance results of 15 metal-poor dwarf stars in the solar neighborhood. Our metallicity measurements are in a good agreement with previous estimates. The stars under investigation have metallicities ranging from -1.6 to -2.8 with the mean value of [Fe/H] = -2.28. The mean values of elemental abundances are [O/Fe] = 0.73, [Na/Fe] = -0.16, [Ca/Fe] = 0.28, and [Ti/Fe] = 0.60. Our results are found to be consistent with those of giant metal-poor stars.
