Abstract
A high angular resolution near-infrared image of a classical TTauri star, DO Tau, was obtained with Coronagraphic Imager with Adaptive Optics (CIAO) mounted on the Subaru Telescope. Circumstellar emission was detected at ∼1".7 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".46 away from the central star. The following observation will reveal whether it is an associated planetary mass object or a background object.
