Nucleosynthesis in Magnetically Driven Jets from Collapsars
Shin-ichiro Fujimoto, Nobuya Nishimura, Masa-aki Hashimoto
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…
Lithium production on a low-mass secondary in a black hole soft X-ray transient
Shin-ichiro Fujimoto, Ryuichi Matsuba, Kenzo Arai
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 f…
Reply to 'Comment on 'Heavy element production in inhomogeneous big bang nucleosynthesis''
Shunji Matsuura, Shin-ichirou Fujimoto, Masa-aki Hashimoto +1
This is a reply report to astro-ph/0604264. We studied heavy element production in high baryon density region in early universe astro-ph/0507439. However it is claimed in astro-ph/…
Heavy element nucleosynthesis in a collapsar
Shin-ichirou Fujimoto, Masa-aki Hashimoto, Kei Kotake +1
We investigate synthesis of heavy elements in a collapsar. We have calculated detailed composition of magnetically driven jets ejected from a collapsar, which is based on long-term…
Magnetohydrodynamic Simulations of A Rotating Massive Star Collapsing to A Black Hole
Shin-ichiro Fujimoto, Kei Kotake, Shoichi Yamada +2
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.…
Heavy Element Production in Inhomogeneous Big Bang Nucleosynthesis
S. Matsuura, S. Fujimoto, S. Nishimura +2
We present a new astrophysical site of the big bang nucleosynthesis (BBN) that are very peculiar compared with the standard BBN. Some models of the baryogenesis suggest that very h…
R-Process Nucleosynthesis in MHD Jet Explosions of Core-Collapse Supernovae
Sunao Nishimura, Kei Kotake, Masa-aki Hashimoto +4
We investigate -process nucleosynthesis during the magnetohydrodynamical (MHD) explosion of supernova in a massive star of 13 . Contrary to the case of the spherical…
Nucleosynthesis inside Gamma-Ray Burst Accretion Disks
S. Fujimoto, M. Hashimoto, K. Arai +1
We investigate nucleosynthesis inside both a gamma-ray burst accretion disk and a wind launched from an inner region of the disk using one-dimensional models of the disk and wind a…
P-Process Nucleosynthesis inside Supernova-Driven Supercritical Accretion Disks
S. Fujimoto, M. Hashimoto, O. Koike +2
We investigate p-process nucleosynthesis in a supercritical accretion disk around a compact object of 1.4 M_solar, using the self-similar solution of an optically thick advection d…
