碩士 === 國立中央大學 === 天文研究所 === 96 === The binary KBOs that make up a fraction of about 10% of the total KBO population are still an enigma. Their formation history and dynamical evolution are closely related to the accretion process and collision processes of the early solar system. A comprehensive census of KBO binaries is therefore an important goal in planetary research. We have initiated just such a project to search for KBO binaries in the distant moving objects data from the Canada France Ecliptic plane Surveys (CFEPS). We also developed a pipeline program to identify the binary object from the CFEPS data. We checked 62 bright objects with good image quality and find a number of possible binaries. One of these was confirmed as a binary. The wide binary fraction of KBOs for this result is about 1/62 and consistent with previous research. However this result is uncertain, so more observations for a binary search are needed.
