Research Abstract
In the present study, a unique method to observe trans-Neptunian objects (TNOs) with radii of 1-10 km (kilometre-sized) has been developed. Since these kilometre-sized TNOs are too faint to detect even with giant telescopes, monitoring of stars has been performed with two small observation systems to detect a small TNO by observing a moment when it hides a brighter background star (stellar occultation). From the two-year observations of the stellar occultations with newly-developed observation systems, a surface number density of kilometre-sized TNOs is obtained.
