Scientific paper

We propose to map three protoplanetary disks with the ATCA, two single sources at 3 mm, and a binary system at 7 mm. By resolving the disks at one wavelength, we will be able to estimate the disk size and derive the surface density profile by model fitting. Using other millimetre data previously obtained with ATCA and in the literature, we will also assess the range of the grain size distribution. By resolving the disks at two wavelengths, we will be able search for signs of dust migration in the disks.
