Evolution Equation of Phenotype Distribution: General Formulation and Application to Error Catastrophe
Katsuhiko Sato, Kunihiko Kaneko
An equation describing the evolution of phenotypic distribution is derived using methods developed in statistical physics. The equation is solved by using the singular perturbation…
Mass spectrum of primordial black holes from inflationary perturbation in the Randall-Sundrum braneworld: a limit on blue spectra
Yuuiti Sendouda, Shigehiro Nagataki, Katsuhiko Sato
The mass spectrum of the primordial black holes formed by density perturbation in the radiation-dominated era of the Randall-Sundrum type-2 cosmology is given. The spectrum coincid…
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.…
Explosive Nucleosynthesis in GRB Jets Accompanied by Hypernovae
Shigehiro Nagataki, Akira Mizuta, Katsuhiko Sato
Two-dimensional hydrodynamic simulations are performed to investigate explosive nucleosynthesis in a collapsar using the model of MacFadyen and Woosley (1999). It is shown that 56N…
