SMSS J022423.27 $-$ 573705.1: An Extremely Metal-Poor Star with the Most Pronounced Weak $r$ -Process Signature

Hiroko Okada, Wako Aoki, Nozomu Tominaga +1

We present the measurement of 26 elemental abundances of SMSS J022423.27 $-$ 573705.1 (SMSS 0224 $-$ 5737), an extremely metal-poor (EMP) star with a weak $r$ -process signature. We rep…

Potassium abundances in extremely metal poor stars: Implications for nucleosynthesis in the final stages of massive star evolution

M. N. Ishigaki, N. Tominaga, W. Aoki +5

We present a potassium (K) abundance analysis in extremely metal-poor (EMP) stars based on high-resolution ( $R \sim 60000$ ) spectra obtained with the High Dispersion Spectrograph on…
