Nucleosynthesis of Pop III and Fe-enriched Pop II Pair-Instability Supernovae

Wenyu Xin, Ken'ichi Nomoto, Chun-Ming Yip +4

Recently discovered very metal-poor (VMP) star LAMOST J1010+2358 shows a peculiar abundance pattern that is remarkably well fit by a Pop III pair-instability supernova (PISN) of $\…

The impact of new ( $α$ , n) reaction rates on the weak s-process in metal-poor massive stars

Wenyu Xin, Chun-Ming Yip, Ken'ichi Nomoto +2

Massive stars are significant sites for the weak s-process (ws-process). $^{22}$ Ne and $^{16}$ O are, respectively, the main neutron source and poison for the ws-process. In the met…
