Collisional fragmentation of dust in protoplanetary disks

Autor: Suyama, Toru, Tanaka, Hidekazu

Publikováno v: 第38回月・惑星シンポジウム = Proceedings of the 38th ISAS Lunar and Planetary Symposium. :37-40

In protoplanetary disk, dust grains grow through mutual collisions, gradually settle to the midplane of a disk. This process is initial condition of planet formation and it is very important process. In many of previous work, they assume that collisi

A planetesimal accretion zone in a circumbinary disk

Autor: Moriwaki, Kazumasa, Nakagawa, Yoshitsugu

Publikováno v: 第36回月・惑星シンポジウム = Proceedings of the 36th ISAS Lunar and Planetary Symposium. :13-16

Until recently, it had been believed that only single solar-type stars might harbor planetary systems. On the other hand, circumbinary disks have been detected by mm/sub-mm wavelength observation. Planets may be formed also in such disks. The conditi

Dust growth and H2O evaporation in protoplanetary disks

Autor: Tanaka, Hidekazu

Publikováno v: 第38回月・惑星シンポジウム = Proceedings of the 38th ISAS Lunar and Planetary Symposium. :41-43

Sub-micrometer sized grains rapidly depletes due to dust growth in realistic weakly turbulent disks if dust disruption is not taken into account. This depletion of sub-micrometer sized grains makes the 10-micrometer silicate feature disappear in the

In situ observations on impact vaporization of water ice

Autor: Sugi, Norio, Arakawa, Masahiko, Kouchi, Akira, Maeno, Norikazu

Publikováno v: 第28回月・惑星シンポジウム = Proceedings of the 28th ISAS Lunar and Planetary Symposium. :33-36

Impact vaporization of ice was an important physical process in the accretion of icy satellites because this process could cause the varieties of the bulk density of these satellites. Thus, we have developed a new experimental equipment to measure th

Measurements of ejection velocities in collisional disruption of ice spheres

Autor: Masahiko Arakawa, Michiya Higa

Publikováno v: 第28回月・惑星シンポジウム = Proceedings of the 28th ISAS Lunar and Planetary Symposium. :37-40

We performed impact experiments on ice spheres to measure the velocity field of ejected ice fragments and considered the conditions under which the fragments would reaccumulate during accretion in the outer solar system. The ejection velocity of fine
