Y. Itohes on the Lie quadric .. has a contact structure, i.e., a globally defined 1-form ω such that ω ∧ (.ω). ≠ 0 on Λ.. This gives rise to a codimension one distribution . on Λ. which has integral submanifolds of dimension .−1, but none of higher dimension. These integral submanifolds are called Legendre

Observational Studies of Interplanetary Dust, knowledge about the dynamics and composition of these local components. We mention sources of interplanetary dust particles revealed by these observations. In the last chapter, we introduce ongoing and future projects related to the observational study of interplanetary dust.

From Protoplanetary Disks to Planetary Disks: Gas Dispersal and Dust Growth,that it is difficult to remove all the disk gas solely by viscous accretion. We discuss photoevaporation as a plausible mechanism for removing the disk gas, and estimate the timescale of gas removal. We then discuss growth of the dust particles into planetesimals. The dust particles first sediment t

Dynamics of Small Bodies in Planetary Systems,s created in the destruction of planetesimals in the disks much in the same way that dust is produced in the asteroid belt and Kuiper belt in the solar system. For the nearest stars, the structure of their debris disks can be directly imaged, showing a wide variety of both axisymmetric and asymmetri

Asteroids and Their Collisional Disruption,nts which kept the memory of collisional processes that took place in different regions of our Solar System during its past and present history. Telescopic observations have collected data of such records, such as the ones provided by asteroid dynamical families and their related dust bands. Meteori
