Europium Isotope Ratios in s-Process-Element-Enhanced, Metal-Poor Stars: A New Probe of the 151Sm Branching
Wako Aoki, Sean G. Ryan, Nobuyuki Iwamoto +6
We report on the first measurement of the Eu isotope fractions (151Eu and 153Eu) in s-process-element-enhanced, metal-poor stars. We use these ratios to investigate the 151Sm branc…

Detection of low Eu abundances in extremely metal-poor stars and the origin of r-process elements
Yuhri Ishimaru, Shinya Wanajo, Wako Aoki +1
We report abundance analyses of three extremely metal-poor stars with [Fe/H] , using the Subaru High Dispersion Spectrograph (HDS). All are found to have sub-solar val…
