Satellite survival in cold dark matter cosmology
C. M. Boily, N. Nakastao, R. Spurzem +1
We study the survival of substructures (clumps) within larger self-gravitating dark matter halos. Building on scaling relations obtained from N-body calculations of violent relaxat…
Evolution of Collisionally Merged Massive Stars
Takeru K. Suzuki, Naohito Nakasato, Holger Baumgardt +3
We investigate the evolution of collisionally merged stars with mass of ~100 MSun which might be formed in dense star clusters. We assumed that massive stars with several tens Msun…
3-D Simulations of the Chemical and Dynamical Evolution of the Galactic Bulge
Naohito Nakasato, Ken'ichi Nomoto
A three-dimensional hydrodynamical N-body model for the formation of the Galaxy is presented with special attention to the formation of the bulge component. Starting with cosmologi…
Metal Enrichment of The Primordial Interstellar Medium through 3-D Hydrodynamical Evolution of The First Supernova Remnant
Naohito Nakasato, Toshikazu Shigeyama
The long-term evolution of supernova remnants (SNRs) in the primordial interstellar medium (ISM) with an inhomogeneous structure is calculated to investigate metal enrichment of th…
Numerical Simulations of Globular Cluster Formation
Naohito Nakasato, Masao Mori, Ken'ichi Nomoto
We examine various physical processes associated with the formation of globular clusters by using the three-dimensional Smoothed Particle Hydrodynamics (SPH) code. Our code include…
Nucleosynthesis in Type Ia Supernovae
K. Nomoto, K. Iwamoto, N. Nakasato +5
Among the major uncertainties involved in the Chandrasekhar mass models for Type Ia supernovae are the companion star of the accreting white dwarf (or the accretion rate that deter…
Smoothed Particle Hydrodynamics with GRAPE and Parallel Virtual Machine
Naohito Nakasato, Masao Mori, Ken'ichi Nomoto
We have developed Remote-GRAPE, a subroutine library to use the special purpose computer GRAPE-3A. The GRAPE-3A can efficiently calculate gravitational force between particles, and…
Instabilities and Mixing in SN 1993J
K. Iwamoto, T. R. Young, N. Nakasato +4
Rayleigh-Taylor (R-T) instabilities in the explosion of SN 1993J are investigated by means of two-dimensional hydrodynamical simulations. It is found that the extent of mixing is s…
