-body Simulation of Planetesimal Formation Through Gravitational Instability of a Dust Layer
Shugo Michikoshi, Shu-ichiro Inutsuka, Eiichiro Kokubo +1
We performed N-body simulations of a dust layer without a gas component and examined the formation process of planetesimals. We found that the formation process of planetesimals ca…
Wave propagation in a weak gravitational field and the validity of the thin lens approximation
Teruaki Suyama, Ryuichi Takahashi, Shugo Michikoshi
Wave effects can be important for the gravitational lensing of gravitational waves. In such a case, wave optics must be used in stead of geometric optics. We consider a plane wave…
Scattering of Gravitational Waves by the Weak Gravitational Fields of Lens Objects
Ryuichi Takahashi, Teruaki Suyama, Shugo Michikoshi
We consider the scattering of the gravitational waves by the weak gravitational fields of lens objects. We obtain the scattered gravitational waveform by treating the gravitational…
The two-fluid analysis of the Kelvin-Helmholtz instability in dusty layer of a protoplanetary disk: A possible path toward the planetesimal formation through the gravitational instability
Shugo Michikoshi, Shu-ichiro Inutsuka
We analyze the stability of dust layer in protoplanetary disk to understand the effect of the relative motion between gas and dust. The previous analyses not including the effect o…
