| Outline of Final Research Achievements |
The goal of this study is to reveal outer environment in the early solar system and migration process of ice giant planets by observing occultations of kilo-meter-size trans-Neptunian objects (TNOs) and deriving their size-frequency distribution. We have developed a wide-field high-speed camera with a field-of-view of 5 deg2 equipped with highly sensitive CMOS sensors and conducted test observations with this camera on the 1-m Schmidt telescope at Kiso observatory, the University of Tokyo to detect the TNO occultations. We have also developed software and observation methods necessary for large surveys for the occultations by researching characteristics of data obtained with this camera in wide-field and high-speed observations in the ecliptic plane and the milky way regions.
