Summary
Our solar system hosts a vast and still unexplored domain. The Oort cloud is the outermost and the largest structure of the solar system but is too distant to be seen even by present-day giant telescopes. I developed observation systems named Organized Autotelescopes for Serendipitous Event Survey (OASES) based on multiple small telescopes, each attached with a high-sensitivity video camera. These systems can detect outer solar system objects indirectly through their stellar occultation events; second scale stellar flux drops when they are passing in front of a star. I will review the previous OASES observation campaign in Miyako Island, Okinawa, and its current status and prospects.
