Abstract

We carried out a homogeneous abundance study for various elements, including α\alpha-elements, iron peak elements and nn-capture elements for 35 metal-poor stars with a wide metallicity range (3.0-3.0\lesssim[Fe/H]0.5\lesssim-0.5). High-resolution (R30R\simeq30k), high signal-to-noise(S/N110S/N\geq110) spectra with a wavelength range of 3800 to 10500 \AA using the Bohyunsan Optical Echelle Spectrograph (BOES). Equivalent widths were measured by means of the Gaussian-fitting method for numerous isolated weak lines of elements. Atmospheric parameters were determined by a self-consistent LTE analysis technique using Fe I and Fe II lines. In this study, we present the EWs of lines and atmospheric parameters for 35 metal-poor stars.
