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 (, 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). Ne and O are, respectively, the main neutron source and poison for the ws-process. In the met…
Impacts of the O(O, n)S reaction rate on the evolution and nucleosynthesis in Pop III massive stars
Wenyu Xin, Ken'ichi Nomoto, Xianfei Zhang +1
We first present a systematic investigation into the effect of the O(O, n)S reaction rate on the evolution and nucleosynthesis of Population III (Pop III) star…
The Impact of C()O Reaction on the Presupernova Evolution and Supernova Explodability of Massive Stars
Wenyu Xin, Ken'ichi Nomoto, Gang Zhao
Among the uncertainties of stellar evolution theory, we investigate how the C()O reaction rate affects the evolution of massive stars for the initial masses o…
