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 $\…

Constraints on the CO and O+O Reaction Rates from Binary Black Holes Detected via Gravitational Wave Signals

Wenyu Xin, Xiaokun Hou, Xianfei Zhang +2

Gravitational-wave observations of binary black hole (BH) mergers provide a novel avenue for testing massive-star evolution and the resulting BH mass spectrum. Recent population an…

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 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…

Relations of rotation and chromospheric activity to stellar age for FGK dwarfs from Kepler and LAMOST

Lifei Ye, Shaolan Bi, Jinghua Zhang +9

The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog, including…

Detection of Solar-like Oscillations in Sub-giant and Red Giant Stars Using 2-minute Cadence TESS Data

Jianzhao Zhou, Shaolan Bi, Jie Yu +7

Based on all 2-minute cadence light curves from Sector 1 to 60, we provide a catalog of 8,651 solar-like oscillators, including frequency at maximum power (, wi…
