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 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…
