Modeling of Collisional Outcomes Based on Impact Simulations of Mars-sized Bodies

Hiroshi Kobayashi, Hidekazu Tanaka, Yukihiko Hasegawa +1

We investigate the outcomes of collisions between Mars-sized bodies through smooth particle hydrodynamics (SPH) simulations, focusing on the transitions among ``merging'', ``hit-an…

Collisional Growth and Fragmentation of Dust Aggregates. II. Mass Distribution of Icy Fragments

Yukihiko Hasegawa, Takeru K. Suzuki, Hidekazu Tanaka +2

By performing -body simulations, we investigated fundamental processes of collisions between dust aggregates composed of submicron-sized icy dust monomers. We examined the mass…

Collisional Growth and Fragmentation of Dust Aggregates with Low Mass Ratios. I: Critical Collision Velocity for Water Ice

Yukihiko Hasegawa, Takeru K. Suzuki, Hidekazu Tanaka +2

We investigated fundamental processes of collisional sticking and fragmentation of dust aggregates by carrying out N-body simulations of submicron-sized icy dust monomers. We exami…

Kelvin-Helmholtz Instabilities in Multi-Sized Dust Layers

Yukihiko Hasegawa, Toru Tsuribe

We examine the effect of the dust size distribution on Kelvin-Helmholtz instabilities in the protoplanetary disk with dust sedimentation. With newly taking into account the dust si…

The Possibility of the Kelvin-Helmholtz Instability during Sedimentation of Dust Grains in the Protoplanetary Disk

Yukihiko Hasegawa, Toru Tsuribe

In this paper, we reexamine the possibility of shear-driven turbulence during sedimentation of dust grains in the protoplanetary disk. The shear-driven turbulence is expected to oc…
