| Research Abstract |
Our project was planned to establish the method of survey of small bodies in the outer region of The solar system, and its application during three years. In the first year, we adjusted the instruments of the Kiso Schmidt telescope at Univ. Tokyo for our survey, Next year we performed survey observations by using this telescope together with the Subaru telescope in the Hawaii branch of National Astron. Obs. Japan. We also developed the software which can discover the small objects automatically from the data taken by those surveys. Although we surveyed forty square degrees of the sky by the Kiso Schmidt telescope, we could not find out any new objects mainly due to the bad weather conditions. However, these experiences made good exercise for actual handling of the data in order to establish the software. As a result, from the data taken by the Subaru telescope, we surveyed one square degree of the sky, and discovered fourteen new objects. This discovery rate is the highest record in the world. In the final year, we improved the softwarewhich made possible foe us to find out much more objects. It is safely said that we established the basic procedure of the survey of the outer solar system. Our results have been reported at the international meeting held at Paris and Spain, and planned to be published as several papers.
