Nucleosynthesis in Magnetically Driven Jets from Collapsars (2008)
Fujimoto, Shin-ichiro, Nishimura, Nobuya, Hashimoto, Masa-aki
We have made detailed calculations of the composition of magnetically driven jets ejected from collapsars, or rapidly rotating massive stars, based on long-term magnetohydrodynamic simulations of...
Lithium production on a low-mass secondary in a black hole soft X-ray transient (2007)
Fujimoto, Shin-ichiro, Matsuba, Ryuichi, Arai, Kenzo
We examine production of Li on the surface of a low-mass secondary in a black hole soft X-ray transient (BHSXT) through the spallation of CNO nuclei by neutrons which are ejected from a hot (> 10...
Magnetohydrodynamic Simulations of A Rotating Massive Star Collapsing to A Black Hole (2006)
Fujimoto, Shin-ichiro, Kotake, Kei, Yamada, Shoichi, Hashimoto, Masa-aki, Sato, Katsuhiko
We perform two-dimensional, axisymmetric, magnetohydrodynamic simulations of the collapse of a rotating star of 40 Msun and in the light of the collapsar model of gamma-ray burst. Considering two...
