Dark matter self-annihilation as a hidden energy source in white dwarfs
Alvin Cheuk-Nam Chu, Cheuk-Man Yiu, Ching-Hui Lam +3
White dwarfs (WDs) are compact remnants of stars, supported by electron degeneracy pressure, and their structures are generally considered to be well understood. Significant discre…
Phase-transition-induced collapse of proto-compact stars and its implication for supernova explosions
Xu-Run Huang, Shuai Zha, Ming-chung Chu +2
A hadron-quark phase transition (PT) may trigger supernova explosions during stellar core collapse. However, both success and failure have occurred in previous attempts to explode…
On the Nucleosynthesis in Accretion-Induced Collapse of White Dwarfs
Chun-Ming Yip, Ming-Chung Chu, Shing-Chi Leung +1
It has long been hypothesized that accretion-induced collapse (AIC) of white dwarfs contribute to heavy chemical elements production in the universe. We present one-dimensional neu…
A new hydrodynamics code for Type Ia Supernovae
S. -C. Leung, M. -C. Chu, L. -M. Lin
A two-dimensional hydrodynamics code for Type Ia supernovae (SNIa) simulations is presented. The code includes a fifth-order shock-capturing scheme WENO, detailed nuclear reaction…
Electron-positron Annihilation Lines and Decaying Sterile Neutrinos
M. H. Chan, M. -C. Chu
If massive sterile neutrinos exist, their decays into photons and/or electron-positron pairs may give rise to observable consequences. We consider the possibility that MeV sterile…
Observational evidences for the existence of 17.4 keV decaying degenerate sterile neutrinos near the Galactic Center
Man Ho Chan, Ming-Chung Chu
We show that the existence of a degenerate halo of sterile neutrinos with rest mass of 17.4 keV near the Galactic Center can account for both the excess 8.7 keV emission observed b…
