Intrinsic properties of the bars formed by the bar instability in flat stellar discs
Shunsuke Hozumi
The properties of the bars formed by the bar instability are examined for flat stellar discs. The initial mass models chosen are Kuzmin--Toomre discs, for which two types of exact…
A Mean-Field Approach to Simulating the Merging of Collisionless Stellar Systems Using a Particle-Based Method
Shunsuke Hozumi, Masaki Iwasawa, Keigo Nitadori
We present a mean-field approach to simulating merging processes of two spherical collisionless stellar systems. This approach is realized with a self-consistent field (SCF) method…
Hydrodynamic simulations of the central molecular zone with realistic Galactic potential
Jihye Shin, Sungsoo S. Kim, Junichi Baba +4
We present hydrodynamic simulations of gas clouds inflowing from the disk to a few hundred parsec region of the Milky Way. A gravitational potential is generated to include realist…
Development of multiple tidal tails around globular clusters and dwarf satellite galaxies
Shunsuke Hozumi, Andreas Burkert
The formation and evolution of tidal tails like those observed around some globular clusters and dwarf satellite galaxies is examined with an N-body simulation. In particular, we a…
Destructible Bars in Disk Galaxies under the Dynamical Influence of a Massive Central Black Hole
Shunsuke Hozumi
The characteristics of the galactic bars that are prone to suffer a damaging impact from a massive central black hole are examined using flat stellar disks. We construct three disk…
Time evolution of galactic warps in prolate haloes
Makoto Ideta, Shunsuke Hozumi, Toshio Tsuchiya +1
A recent observation with the Hipparcos satellite and some numerical simulations imply that the interaction between an oblate halo and a disc is inappropriate for the persistence o…
