| Outline of Final Research Achievements |
Impact events such as giant impacts should play a significant role in the planet formation processes. In this study, we made various observations of debris disks and other objects that could be related to impact events and dust generation, and investigated the behavior of dust grains in multiple systems. We discovered some new candidates of warm debris disks, and succeeded to obtain the physical and chemical characteristics of debris dust around some systems. We also found the temporal variability of the mid-infrared brightness contrast in Saturn's rings, and discussed its origin.
