Özet:

 This study introduces a line list for the abundance analysis of F-and G-type stars across the 40809675 Å wavelength range. A systematic search employing lower excitation potentials, accurate log  values, and an updated multiplet table led to the identification of 592 lines across 33 species 25 elements, including C, O, Mg ionized, Al, P, S, Cu, Zr neutral, and La. To determine the uncertainties in log  values, we assessed solar abundance using a very high-resolution  1000000 disk integrated solar spectrum. These lines were confirmed to be blend-free in the solar spectrum. The line list was further validated by analyzing the metal-poor star HD218209 G6V, which is notable for its well-documented and reliable abundance in literature. The abundances were obtained using the equivalent width EW method and further refined by applying the spectrum synthesis method. A comparative analysis with the Gaia-ESO line list v.6, provided by the Gaia-ESO collaboration, revealed additional neutral and ionized Fe lines. This extensively refined line list will facilitate precise stellar parameter determinations and accurate abundance analyses of spectra within the PolarBASE spectral library.
