Influence of effective mass of the relativistic mean field theory on core collapse supernovae and compact objects
Kohsuke Sumiyoshi, Hajime Togashi, Shun Furusawa +4
We study the influence of the effective mass in the relativistic mean field (RMF) theory on the properties of the central core of collapse-driven supernovae and the formation of co…
Impact of Effective Nucleon Mass and Multineutron States on the Equation of State for Core-Collapse Supernovae
Tatsuya Matsuki, Shun Furusawa, Kohsuke Sumiyoshi +2
In this study, we investigate the impact of effective nucleon mass and the existence of the dineutron and the tetraneutron on the thermodynami…
Bifurcated Impact of Neutrino Fast Flavor Conversion on Core-collapse Supernovae Informed by Multi-angle Neutrino Radiation Hydrodynamics
Ryuichiro Akaho, Hiroki Nagakura, Wakana Iwakami +6
In this {\it Letter}, we present a compelling and robust argument for the roles of neutrino fast flavor conversion (FFC) in the explosion mechanism of core-collapse supernova (CCSN…
Role of symmetry energy at subnuclear densities in protoneutron star crusts
Ken'ichiro Nakazato, Hajime Togashi, Kohsuke Sumiyoshi +1
The impact of matter properties at subnuclear densities on the evolution of protoneutron stars is investigated. Several models of nuclear equation of state (EOS) are constructed wi…
Observing Supernova Neutrino Light Curves with Super-Kamiokande.VI. A Practical Data Analysis Technique Considering Realistic Experimental Backgrounds
Fumi Nakanishi, Ken'ichiro Nakazato, Masayuki Harada +9
Neutrinos from supernovae, especially those emitted during the late phase of core collapse, are essential for understanding the final stages of massive star evolution. We have been…
Neutrino flavor instabilities in a binary neutron star merger remnant: Roles of a long-lived hypermassive neutron star
Hiroki Nagakura, Kohsuke Sumiyoshi, Sho Fujibayashi +2
Understanding the post-merger evolution of binary neutron star merger (BNSM) requires accurate modeling of neutrino transport and microphysics including neutrino flavor conversions…
