项目摘要

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.

我们的项目计划用三年时间建立太阳系外区域小天体的测量方法，并进行应用。第一年，我们调整了东京大学的Kiso Schmidt望远镜的仪器来进行我们的调查，明年我们将使用这个望远镜和美国国家宇航中心夏威夷分部的斯巴鲁望远镜进行调查观测。奥林匹克广播服务公司。日本。我们还开发了从这些调查数据中自动发现小物体的软件。虽然我们用基索·施密特望远镜观测了40平方度的天空，但主要由于恶劣的天气条件，我们没有发现任何新的物体。然而，这些经验为实际处理数据以建立软件提供了很好的练习。结果，根据斯巴鲁望远镜拍摄的数据，我们调查了一平方度的天空，发现了14个新物体。这个发现速度是世界上最高的记录。在最后一年，我们改进了软件，使我们有可能找到更多的对象。可以有把握地说，我们建立了调查外太阳系的基本程序。我们的研究结果已经在巴黎和西班牙举行的国际会议上报告，并计划以几篇论文的形式发表。
