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…

Dust coagulation assisted by streaming instability in protoplanetary disks
Ryosuke T. Tominaga, Hidekazu Tanaka
The streaming instability is a promising mechanism for planetesimal formation. The instability can rapidly form dense clumps that collapse self-gravitationally, which is efficient…
