Modeling the Contact Surfaces Formed by Pebble Collisions: Application to Formation of Comet 67P/Churyumov--Gerasimenko
Misako Tatsuuma, Satoshi Okuzumi, Akimasa Kataoka +1
Modeling the contact surfaces formed by pebble collisions is crucial to understanding the formation process of comets, which are thought to be composed of pebbles. In this paper, w…
Investigating the Bouncing Barrier with Collision Simulations of Compressed Dust Aggregates
Haruto Oshiro, Misako Tatsuuma, Satoshi Okuzumi +1
The collision outcomes of dust aggregates in protoplanetary disks dictate how planetesimals form. Experimental and numerical studies have suggested that bouncing collisions occurri…
A closer look at individual collisions of dust aggregates: Material mixing and exchange on microscopic scales
Sebastiaan Krijt, Sota Arakawa, Mark Oosterloo +1
Collisions between aggregates with different histories and compositions are expected to be commonplace in dynamically active protoplanetary discs. Nonetheless, relatively little is…
On the elastoplastic behavior in collisional compression of spherical dust aggregates
Sota Arakawa, Hidekazu Tanaka, Eiichiro Kokubo +4
Aggregates consisting of submicron-sized cohesive dust grains are ubiquitous, and understanding the collisional behavior of dust aggregates is essential. It is known that low-speed…
The Bulk Densities of Small Solar System Bodies as a Probe of Planetesimal Formation
Misako Tatsuuma, Akimasa Kataoka, Hidekazu Tanaka +1
Constraining the formation processes of small solar system bodies is crucial for gaining insights into planetesimal formation. Their bulk densities, determined by their compressive…
Electric charging of dust aggregates and its effect on dust coagulation in protoplanetary disks
Satoshi Okuzumi
Mutual sticking of dust aggregates is the first step toward planetesimal formation in protoplanetary disks. In spite that the electric charging of dust particles is well recognized…
