A high angular resolution near-infrared image of a classical T Tauri star, DO Tau, was obtained with Coronagraphic Imager with Adaptive Optics (CIAO) mounted on the Subaru Telescope. Circumstellar emission was detected at [math] from the central star in the direction of the redshifted jet. No emission was found toward the opposite direction. We also found one faint point source 3[math]46 away from the central star. The following observation will reveal whether it is an associated planetary mass object or a background object.

Keywords: stars: individual (DO Taurus); stars: pre-main sequence; techniques: high angular resolution
