New Insights into Uncertainties in the Relic Neutrino Background and Effects from the Nuclear Equation of State
Grant J. Mathews, Luca Boccioli, Jun Hidaka +1
We review the computation of and associated uncertainties in the current understanding of the relic neutrino background due to core-collapse supernovae, black hole formation and ne…
Stellar Abundances for Galactic Archaeology Database IV - Compilation of Stars in Dwarf Galaxies
Takuma Suda, Jun Hidaka, Wako Aoki +7
We have constructed the database of stars in the local group using the extended version of the SAGA (Stellar Abundances for Galactic Archaeology) database that contains stars in 24…
Early chemo-dynamical evolution of dwarf galaxies deduced from enrichment of r-process elements
Yutaka Hirai, Yuhri Ishimaru, Takayuki R. Saitoh +3
The abundance of elements synthesized by the rapid neutron-capture process (r-process elements) of extremely metal-poor (EMP) stars in the Local Group galaxies gives us clues to cl…
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…
Sterile neutrino dark matter and core-collapse supernovae
Grant J. Mathews, MacKenzie Warren, Jun Hidaka +1
We have explored the impact of sterile neutrino dark matter on core-collapse supernova explosions. We have included oscillations between electron neutrinos or mixed neutrinos…
Impact of sterile neutrino dark matter on core-collapse supernovae
MacKenzie L. Warren, Grant J. Mathews, Matthew Meixner +2
We summarize the impact of sterile neutrino dark matter on core-collapse supernova explosions. We explore various oscillations between electron neutrinos or mixed neutrinos a…
Enrichment of r-process elements in dwarf spheroidal galaxies in chemo-dynamical evolution model
Yutaka Hirai, Yuhri Ishimaru, Takayuki R. Saitoh +3
The rapid neutron-capture process (r-process) is a major process to synthesize elements heavier than iron, but the astrophysical site(s) of r-process is not identified yet. Neutron…
Asymmetric Neutrino Production in Strongly Magnetized Proto-Neutron Stars
Tomoyuki Maruyama, Myung-Ki Cheoun, Jun Hidaka +6
We calculate the neutrino production cross-section through the direct URCA process in proto-neutron star matter in the presence of a strong magnetic field. We assume isoentropic co…
Supernova Relic Neutrinos and the Supernova Rate Problem: Analysis of Uncertainties and Detectability of ONeMg and Failed Supernovae
Grant J. Mathews, Jun Hidaka, Toshitaka Kajino +1
Direct measurements of the core-collapse supernova rate in the redshift range 0<z 1 appear to be about a factor of two smaller than the rate inferred from the measured cosmic massi…
Sterile neutrino oscillations in core-collapse supernovae
MacKenzie L. Warren, Matthew Meixner, Grant Mathews +2
We have made core-collapse supernova simulations that allow oscillations between electron neutrinos (or their anti particles) with right-handed sterile neutrinos. We have considere…
Rapid Spin Deceleration of Magnetized Proto-Neutron Stars via Asymmetric Neutrino Emission
T. Maruyama, J. Hidaka, T. Kajino +5
We calculate the spin deceleration of proto-neutron stars by asymmetric neutrino absorption in the context of a fully relativistic mean field theory. We calculate for the first tim…
Relativistic Mean-Field Treatment of Pulsar Kick from Neutrino Propagation in Magnetized Proto-Neutron
Tomoyuki Maruyama, Nobutoshi Yasutake, Myung-Ki Cheoun +3
We make a perturbative calculation of neutrino scattering and absorption in hot and dense hyperonic neutron-star matter in the presence of a strong magnetic Field. We calculate tha…
Sterile Neutrino-Enhanced Supernova Explosions
Jun Hidaka, George M. Fuller
We investigate the enhancement of lepton number, energy, and entropy transport resulting from active-sterile neutrino conversion deep in the post-bounce supernova core…
Dark matter sterile neutrinos in stellar collapse: alteration of energy/lepton number transport and a mechanism for supernova explosion enhancement
Jun Hidaka, George M. Fuller
We investigate matter-enhanced Mikheyev-Smirnov-Wolfenstein (MSW) active-sterile neutrino conversion in the channel in the collapse of the iron core of…
