Publikováno v: 第39回月・惑星シンポジウム = Proceedings of the 39th ISAS Lunar and Planetary Symposium. :139-142
We have carried out numerical simulations of head-on collisions of 2-D dust aggregates to investigate the compression and disruption processes of aggregates due to mutual collisions. Although similar numerical simulations have been conducted by Domin

Autor: Nakamoto, Taishi, Kadono, Toshihiko, Arakawa, Masahiko
Publikováno v: 第39回月・惑星シンポジウム = Proceedings of the 39th ISAS Lunar and Planetary Symposium. :17-20
We have examined if the shock-wave heating chondrule formation model forms compound chondrules. Especially, we focus on the formation process of compound chondrules by collisions. In the shock wave heating process, stripping off of liquid surface fro

Publikováno v: 第39回月・惑星シンポジウム = Proceedings of the 39th ISAS Lunar and Planetary Symposium. :9-12
Although chondrules formed under levitated environment in space, most of the previous experiments were non-levitated experiments. We carried out the levitated experiments by using a gas jet levitator. The experimental results show that nucleation of
