Early chemo-dynamical evolution of dwarf galaxies deduced from enrichment of r-process elements
Yutaka Hirai, Yuhri Ishimaru, Takayuki R. Saitoh +3
The abundance of elements synthesized by the rapid neutron-capture process (r-process elements) of extremely metal-poor (EMP) stars in the Local Group galaxies gives us clues to cl…
Chemical evolution library for galaxy formation simulation
Takayuki R. Saitoh
We have developed a software library for chemical evolution simulations of galaxy formation under the simple stellar population (SSP) approximation. In this library, all of the nec…
Eventful Evolution of Giant Molecular Clouds in Dynamically Evolving Spiral Arms
Junichi Baba, Kana Morokuma-Matsui, Takayuki R. Saitoh
The formation and evolution of giant molecular clouds (GMCs) in spiral galaxies have been investigated in the traditional framework of the combined quasi-stationary density wave an…
Santa Barbara Cluster Comparison Test with DISPH
Takayuki Saitoh, Junichiro Makino
The Santa Barbara cluster comparison project (Frenk et al. Frenk+1999) revealed that there is a systematic difference between entropy profiles of clusters of galaxies obtained by E…
A comparison of SPH artificial viscosities and their impact on the Keplerian disk
Natsuki Hosono, Takayuki R. Saitoh, Junichiro Makino
Hydrodynamical simulations of rotating disk play important roles in the field of astrophysical and planetary science. Smoothed Particle Hydrodynamics (SPH) has been widely used for…
The Giant Impact Simulations with Density Independent Smoothed Particle Hydrodynamics
Natsuki Hosono, Takayuki R. Saitoh, Junichiro Makino +2
At present, the giant impact (GI) is the most widely accepted model for the origin of the Moon. Most of the numerical simulations of GI have been carried out with the smoothed part…
