Delayed Detonation Thermonuclear Supernovae With An Extended Dark Matter Component
H-S. Chan, M-C. Chu, S-C. Leung +1
We present simulations of thermonuclear supernovae admixed with an extended component of fermionic cold dark matter. We consider the explosion of a Chandrasekhar-mass white dwarf u…
Exploration of Aspherical Ejecta Properties in Type Ia Supernova: Progenitor Dependence and Applications to Progenitor Classification
Shing-Chi Leung, Roland Diehl, Ken'ichi Nomoto +1
Several explosions of thermonuclear supernovae (SNe Ia) have been found to exhibit deviations from spherical symmetry upon closer inspection. Examples are the gamma-ray lines from…
Hydrodynamic Simulations of Pre-Supernova Outbursts in Red Supergiants: Asphericity and Mass Loss
Shing-Chi Leung, Jim Fuller
The activity of massive stars approaching core-collapse can strongly affect the appearance of the star and its subsequent supernova. Late-phase convective nuclear burning generates…
A Model for Fast Blue Optical Transient AT2018Cow: Circumstellar Interaction of a Pulsational Pair-instability Supernova
Shing-Chi Leung, Sergei Blinnikov, Ken'ichi Nomoto +3
The Fast Blue Optical Transient (FBOT) ATLAS18qqn (AT2018cow) has a light curve as bright as superluminous supernovae but rises and falls much faster. We model this light curve by…
Explosive Nucleosynthesis in Near-Chandrasekhar-mass White Dwarf Models for Type Iax Supernovae: Dependence on Model Parameters
Shing-Chi Leung, Ken'ichi Nomoto
The recently observed diversity of Type Ia supernovae (SNe Ia) has motivated us to conduct the theoretical modeling of SNe Ia for a wide parameter range. In particular, the origin…
Pulsational Pair-instability Supernovae. II. Neutrino Signals from Pulsations and their Detection by Terrestrial Neutrino Detectors
Shing-Chi Leung, Sergei Blinnikov, Koji Ishidoshiro +2
A Pulsational Pair-instability supernova (PPISN) evolves from a massive star with a mass -- 140 which develops the electron-positron pair-instability after th…
Three-dimensional Models of Core-collapse Supernovae From Low-mass Progenitors With Implications for Crab
G. Stockinger, H. -Th. Janka, D. Kresse +9
We present 3D full-sphere supernova simulations of non-rotating low-mass (~9 Msun) progenitors, covering the entire evolution from core collapse through bounce and shock revival, t…
Chemical abundances in Sgr A East: evidence for a Type Iax supernova remnant
Ping Zhou, Shing-Chi Leung, Zhiyuan Li +3
Recent observations have shown a remarkable diversity of observational behaviors and explosion mechanisms in thermonuclear supernovae (SNe). An emerging class of peculiar thermonuc…
Standing on the shoulders of giants: New mass and distance estimates for Betelgeuse through combined evolutionary, asteroseismic, and hydrodynamical simulations with MESA
Meridith Joyce, Shing-Chi Leung, László Molnár +3
We conduct a rigorous examination of the nearby red supergiant Betelgeuse by drawing on the synthesis of new observational data and three different modeling techniques. Our observa…
