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…
Measuring the Low-Energy Weak Mixing Angle with Supernova Neutrinos
Chun-Ming Yip, Xu-Run Huang, Ming-chung Chu +1
The weak mixing angle is a fundamental parameter in the electroweak theory with a value running according to the energy scale, and its precision measurement in the low-energ…
R-process Nucleosynthesis of Subminimal Neutron Star Explosions
Chun-Ming Yip, Ming-Chung Chu, Shing-Chi Leung +1
We show that a minimum-mass neutron star undergoes delayed explosion after mass removal from its surface. We couple the Newtonian hydrodynamics to a nuclear reaction network of $\s…
Universal Relations for Elastic Hybrid Stars and Quark Stars
Chun-Ming Yip, Shu Yan Lau, Kent Yagi
Some compact stars may contain deconfined quark matter, forming hybrid stars or quark stars. If the quark matter forms an inhomogeneous condensate in the crystalline color supercon…
