Temperature-resolved sensitivities of production to helium-burning reactions in pair-instability supernovae
Hiroki Kawashimo, Nobuya Nishimura, Yudai Suwa
We propose a temperature-resolved Monte Carlo (MC) approach to identify the temperature regimes in which low-energy helium-burning reaction rates most strongly affect nucleosynthes…
From supernovae to neutron stars: crust formation time
Yudai Suwa, Ken'ichiro Nakazato
A neutron star is born as a hot, lepton-rich protoneutron star (PNS) and cools via neutrino emission, eventually allowing heavy ions in the outer layers to crystallize into a solid…
Impacts of hydrogen envelope on supernova fallback and the resulting compact remnant masses
Kengo Shinoda, Yudai Suwa, Ryosuke Hirai +4
Fallback in core-collapse supernovae plays a central role in setting compact-remnant masses and may produce late-time emission. In hydrogen rich progenitors, the reverse shock aris…
Cosmic-Ray Bath in a Past Supernova Gives Birth to Earth-Like Planets
Ryo Sawada, Hiroyuki Kurokawa, Yudai Suwa +3
A key question in astronomy is how ubiquitous Earth-like rocky planets are. The formation of terrestrial planets in our solar system was strongly influenced by the radioactive deca…
Destratification in the Progenitor Interior of the Mg-rich Supernova Remnant N49B
Toshiki Sato, Kai Matsunaga, Ryo Sawada +6
Simulations of pre-supernova evolution suggest that some intense shell burning can be so active that, in extreme cases, it can merge with the outer shell, changing the initial cond…
Self-consistent Conditions for Al Injection into Protosolar Disk from a Nearby Supernova
Ryo Sawada, Tetsuo Taki, Hiroyuki Kurokawa +1
The early solar system contained a short-lived radionuclide, Al (its half-life time Myr). The decay energy Al is thought to have controlled the therma…
