Investigation of the Physical Properties of Protoplanetary Disks around T Tauri Stars by a High-resolution Imaging Survey at lambda = 2 mm
Dust continuum emission at 2 millimeters from the disks around 13 T Tauri stars was imaged with the spatial resolution of 1''-2''. Disk properties are derived from the combination of image-based model fitting and the analysis of the spectral energy distributions. We found a tendency for disk expansion with decreasing accretion activity, which can be interpreted in terms of the evolution of an accretion disk. The derived surface density distribution of the disks may suggest that it is difficult to make planets like the solar system without the redistribution of solids.
