Jetting during oblique impacts of spherical impactors
Shigeru Wakita, Brandon Johnson, C. Adeene Denton +1
During the early stages of an impact a small amount material may be jetted and ejected at speeds exceeding the impact velocity. Jetting is an important process for producing melt d…
Aggregate Growth and Internal structures of Chondrite Parent Bodies Forming from Dense Clumps
Yuji Matsumoto, Shigeru Wakita, Yasuhiro Hasegawa +1
Major components of chondrites are chondrules and matrix. Measurements of the volatile abundance in Semarkona chondrules suggest that chondrules formed in a dense clump that had a…
The Properties of Planetesimal Collisions under Jupiter's Perturbation and the Application to Chondrule Formation via Impact Jetting
Shoichi Oshino, Yasuhiro Hasegawa, Shigeru Wakita +1
Understanding chondrule formation provides invaluable clues about the origin of the solar system. Recent studies suggest that planetesimal collisions and the resulting impact melts…
Fates of hydrous materials during planetesimal collisions
Shigeru Wakita, Hidenori Genda
Hydrous minerals are found on the surfaces of asteroids, but their origin is not clear. If their origin is endogenic, the hydrous minerals that were formed in the inner part of a p…
Abundances of ordinary chondrites in thermally evolving planetesimals
S. Wakita, Y. Hasegawa, T. Nozawa
Chondrites are one of the most primitive objects in the solar system, and keep the record of the degree of thermal metamorphism experienced in their parent bodies. This thermal his…
Chondrule Accretion with a Growing Protoplanet
Yuji Matsumoto, Shoichi Oshino, Yasuhiro Hasegawa +1
Chondrules are primitive materials in the Solar System. They are formed in the first about 3 Myr of the Solar System's history. This timescale is longer than that of Mars formation…
