Modifications of SPH towards three-dimensional simulations of an icy moon with internal ocean
Keiya Murashima, Natsuki Hosono, Takayuki R. Saitoh +1
There are some traces of the existence of internal ocean in some icy moons, such as the vapor plumes of Europa and Enceladus. This implies a region of liquid water beneath the surf…
Effect of Equation of State and Cutoff Density in Smoothed Particle Hydrodynamics Simulations of the Moon-Forming Giant Impact
Scott D. Hull, Miki Nakajima, Natsuki Hosono +2
The amount of vapor in the impact-generated protolunar disk carries implications for the dynamics, devolatilization, and moderately volatile element (MVE) isotope fractionation dur…
Merging Criteria for Planetesimal Collisions
Takashi Shibata, Eiichiro Kokubo, Natsuki Hosono
In the standard scenario of planet formation, terrestrial planets, ice giants, and cores of gas giants are formed by the accumulation of planetesimals. However, there are few N-bod…
N-body Simulations of Ring Formation Process around the Dwarf Planet Haumea
Iori Sumida, Yuya Ishizawa, Natsuki Hosono +1
Haumea is the only known trans-Neptunian object with a ring. The ring is in a position that causes a 3:1 spin-orbit resonance with the rotational period of Haumea, which has a tria…
Can the Uranian Satellites Form from a Debris Disk Generated by a Giant Impact?
Yuya Ishizawa, Takanori Sasaki, Natsuki Hosono
Hydrodynamic simulations of a giant impact to proto-Uranus indicated that such an impact could tilt its rotational axis and produce a circumplanetary debris disk beyond the corotat…
Particle Number Dependence of The -Body Simulations of Moon Formation
Takanori Sasaki, Natsuki Hosono
The formation of the Moon from the circumterrestrial disk has been investigated by using -body simulations with the number of particles limited from to . We dev…
Unconvergence of Very Large Scale GI Simulations
Natsuki Hosono, Masaki Iwasawa, Ataru Tanikawa +3
The giant impact (GI) is one of the most important hypotheses both in planetary science and geoscience, since it is related to the origin of the Moon and also the initial condition…
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…
