Potassium Abundances in Extremely Metal Poor Stars: Implications for Nucleosynthesis in the Final Stages of Massive Star Evolution
We present a potassium (K) abundance analysis in extremely metal-poor (EMP) stars based on high-resolution ( R ∼ 60,000) spectra obtained with the High Dispersion Spectrograph on the Subaru Telescope, covering the K i resonance lines at 766 and 769 nm. One-dimensional local thermodynamic equilibriu...
