Atomic Line List for Chemical Abundance Analysis of F- and G-Type Stars

A curated catalog of atomic spectral lines — with excitation potentials, oscillator strengths (log gf), and multiplet data — selected to be blend-free for measuring elemental abundances in Sun-like (F and G) stars across optical to near-infrared wavelengths. Such a line list, calibrated on the solar spectrum and validated on a benchmark metal-poor star, underpins precise stellar-parameter and abundance determinations.
