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…
Impact of dineutrons on nuclear compositions of a core-collapse supernova
Tatsuya Matsuki, Shun Furusawa, Katsuhiko Suzuki
We study the nuclear compositions in the central region of a core-collapse supernova, assuming the existence of dineutrons () and tetraneutrons (). At 100~ms after core b…
Nuclei in Core-Collapse Supernovae Engine
Shun Furusawa, Hiroki Nagakura
Herein, we review the nuclear equations of state (EOSs) %for core-collapse supernova simulations and the constituent nuclei of core-collapse supernovae (CCSNe) and their roles in C…
Equation of state in neutron stars and supernovae
Kohsuke Sumiyoshi, Toru Kojo, Shun Furusawa
Neutron stars and supernovae provide cosmic laboratories of highly compressed matter at supra nuclear saturation density which is beyond the reach of terrestrial experiments. The p…
Quantum statistical effects in warm nuclear matter with light and heavy clusters
Shun Furusawa, Igor Mishustin
We have investigated the compositions of hot and dense nuclear matter with the focus on the quantum-statistical effects for light clusters. Our main observation is that the formati…
Sensitivity of nuclear statistical equilibrium to nuclear uncertainties during stellar core collapse
Shun Furusawa
I have systematically investigated the equations of state (EOSs) in nuclear statistical equilibrium under thermodynamic conditions relevant for core collapse of massive stars by va…
