Abstract

We present high spatial resolution observations of disks around young stellar objects in Taurus with the Nobeyama Millimeter Array. A survey of circumstellar disks at 3 mm shows that the 3 mm continuum emission tends to be weaker for embedded sources than for visible T Tauri stars, which is consistent with our previous interpretation of protoplanetary disk formation. The CS gas around L1489 and IRAS 04365+2535 show disk-like structures of ∼1000 AU in radius. A 13CO observation of HL Tau indicates direct evidence of dynamical infalling motion. We discuss the formation of a centrifugally supported viscous accretion disk around HL Tau.
