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

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

The motion of dust grains, released from comet Shoemaker-Levy 9 (SL9), has been examined, considering the influence of the Jovian magnetosphere. Especially, reentering of these grains to the Jovian magnetosphere in the middle of July 1994 is studied.

We have examined the origin of beta-meteoroids based on the sublimation of circumsolar dust grains. Orbital evolutions of particles starting to sublime at 8 solar radius have been studied. It is found that some of these particles with initial radii r

The emission feature around 11.3 micrometer observed towards carbon stars is considered to be due to SiC grains condensed in the circumstellar envelopes. The isotopic anomalies of SiC discovered in carbonaceous meteorites strongly support the formati
