An Updated Line List for Spectroscopic Investigation of G Stars- II: Refined Solar Abundances via Extended Wavelength Coverage to 10,000 Å

Abstract

This study introduces a line list for the abundance analysis of F-and G-type stars across the 4080–9675 Å wavelength range. A systematic search employing lower excitation potentials, accurate log𝑔 𝑓 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 log𝑔 𝑓 values, we assessed solar abundance using a very high-resolution (𝑅 ≈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.
