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…
Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors
Tomoki Matsuoka, Ryo Sawada
Recent observations of supernovae (SNe) have indicated that a fraction of massive stars possess dense circumstellar medium (CSM) at the moment of their core collapses. They suggest…
Gravitational Collapse of White Dwarfs to Neutron Stars. I. From Initial Conditions to Explosions with Neutrino-radiation Hydrodynamics Simulations
Masamitsu Mori, Ryo Sawada, Yudai Suwa +3
This paper provides collapses of massive, fully convective, and non-rotating white dwarfs (WDs) formed by accretion-induced collapse or merger-induced collapse and the subsequent e…
Impacts of the reaction rate on nucleosynthesis in pair-instability supernovae
Hiroki Kawashimo, Ryo Sawada, Yudai Suwa +3
Nuclear reactions are key to our understanding of stellar evolution, particularly the rate, which is known to significantly influence the…
Updating the Ni Problem in Core-collapse Supernova Explosion
Ryo Sawada, Yudai Suwa
Details of the core-collapse supernova (CCSN) explosion mechanism still need to be fully understood. There is an increasing number of successful examples of reproducing explosions…
