| Outline of Final Research Achievements |
The goal of this study is to derive a size-frequency distribution of kilo-meter size trans-Neptunian objects (TNOs) and reveal the outer environment in the early solar system and migration process of ice giant planets by observing stellar occultations due to the TNOs. To accomplish this purpose, we have completed a wide-field video camera for the Kiso 105-cm Schmidt telescope and conducted a wide-field video survey of the sky at 2 Hz for a long period. While we could not detect stellar occultations due to the TNOs in the period of this study, we have successfully developed an observation system for the occultations.
