Two-dimensional models of core-collapse supernova explosions assisted by heavy sterile neutrinos
Kanji Mori, Tomoya Takiwaki, Kei Kotake +1
Core-collapse supernovae can be a copious source of sterile neutrinos, hypothetical particles that mix with active neutrinos. We develop two-dimensional stellar core-collapse model…
Multi-messenger signals of heavy axionlike particles in core-collapse supernovae: two-dimensional simulations
Kanji Mori, Tomoya Takiwaki, Kei Kotake +1
Core-collapse supernovae are a useful laboratory to probe the nature of exotic particles. If axionlike particles (ALPs) are produced in supernovae, they can affect the transfer of…
Ambipolar Heating of Magnetars
Sachiko Tsuruta, Madeline J. Kelly, Ken'ichi Nomoto +3
Magnetars, neutron stars thought to be with ultra-strong magnetic fields of G, are observed to be much hotter than ordinary pulsars with G, and additi…
Light Curves and Event Rates of Axion Instability Supernovae
Kanji Mori, Takashi J. Moriya, Tomoya Takiwaki +3
It was recently proposed that exotic particles can trigger a new stellar instability which is analogous to the e-e+ pair instability if they are produced and reach equilibrium in t…
Evolution of Urca Pairs in the Crusts of Highly Magnetized Neutron Stars
Michael Famiano, Grant Mathews, A. Baha Balantekin +3
We report on the effects of strong magnetic fields on neutrino emission in the modified Urca process. We show that the effect of Landau levels on the various Urca pairs affects the…
Shock Revival in Core-collapse Supernovae Assisted by Heavy Axion-like Particles
Kanji Mori, Tomoya Takiwaki, Kei Kotake +1
Axion-like particles (ALPs) are a class of hypothetical pseudoscalar particles which feebly interact with ordinary matter. The hot plasma of core-collapse supernovae is a possible…
Screening Effects on Electron Capture Rates and Type Ia Supernova Nucleosynthesis
Kanji Mori, Toshio Suzuki, Michio Honma +4
Type Ia supernovae (SNe Ia) are believed to be a thermonuclear explosion of a white dwarf, but the mass of their progenitors is still an open problem. In near-Chandrasekhar-mass (n…
Nuclear Reaction Screening, Weak Interactions, and r-Process Nucleosynthesis in High Magnetic Fields
Michael Famiano, A. Baha Balantekin, Toshitaka Kajino +3
Coulomb screening and weak interactions in a hot, magnetized plasma are investigated. Coulomb screening is evaluated in a relativistic thermal plasma in which electrons and positro…
Impacts of the New Carbon Fusion Cross Sections on Type Ia Supernovae
Kanji Mori, Michael A. Famiano, Toshitaka Kajino +2
Type Ia supernovae (SNe Ia) are thought to be thermonuclear explosion of white dwarfs (WDs). Their progenitors are not well understood. One popular scenario is the double-degenerat…
Nucleosynthesis Constraints on the Explosion Mechanism for Type Ia Supernovae
Kanji Mori, Michael A. Famiano, Toshitaka Kajino +6
Observations of type Ia supernovae include information about the characteristic nucleosynthesis associated with these thermonuclear explosions. We consider observational constraint…
Impact of New Gamow-Teller Strengths on Explosive Type Ia Supernova Nucleosynthesis
Kanji Mori, Michael A. Famiano, Toshitaka Kajino +6
Recent experimental results have confirmed a possible reduction in the GT strengths of pf-shell nuclei. These proton-rich nuclei are of relevance in the deflagration and explos…
