Abstract

Many classical T Tauri stars have proto-planetary disks. However since such structures are very faint, observations with high spatial resolution and huge dynamic range are required. We have carried out near-infrared coronagraphic observations of DO Tau and detected very faint structure at 160 AU from the central star. With its morphology, we consider it as a proto-planetary disk.
