The appearance of a 'fresh' surface on 596 Scheila as a consequence of the 2010 impact event
Sunao Hasegawa, Michael Marsset, Francesca E. DeMeo +8
Dust emission was detected on main-belt asteroid 596 Scheila in December 2010, and attributed to the collision of a few-tens-of-meters projectile on the surface of the asteroid. In…
Crater shape as a possible record of the impact environment of metallic bodies: Effects of temperature, impact velocity and impactor density
Ryo Ogawa, Akiko M. Nakamura, Ayako I. Suzuki +1
Metallic bodies that were the cores of differentiated bodies are sources of iron meteorites and are considered to have formed early in the terrestrial planet region before migratin…
Packing fraction of clusters formed in free-falling granular streams based on flash X-ray radiography
Yuuya Nagaashi, Akiko M. Nakamura, Sunao Hasegawa +1
We study the packing fraction of clusters in free-falling streams of spherical and irregularly shaped particles using flash X-ray radiography. The estimated packing fraction of clu…
Primordial porous structure of chondrite parent bodies due to self-gravity
Tomomi Omura, Akiko M. Nakamura
The porosity of an asteroid is important when studying the evolution of our solar system through small bodies and for planning mitigation strategies to avoid disasters due to aster…
Cohesion of regolith: Measurements of meteorite powders
Yuuya Nagaashi, Takanobu Aoki, Akiko M. Nakamura
The cohesion of particles has a significant effect on the properties of small bodies. In this study, we measured in open air, the cohesive forces of tens of micron-sized irregularl…
