We obtained high resolution (~0.1) near-infrared images of UY Aur using the Coronagraphic Imager with Adaptive Optics (CIAO) on the Subaru Telescope. UY Aur is classical T Tauri binary systems. We detected a half-ring shaped circumbinary disk around UY Aur. It has a clumpy structure along the disk and a cavity between the binary and the disk. The lower limit of the clump mass is calculated to be ~9.6 earth mass, assuming optically thin conditions in near-infrared.
