A comparison of OSCIR images of the protoplanetary disk of HR4796A. With Keck details are resolved.
CTIO 4-metre against
Keck II 10-metre
8-25 AU resolution will be obtained at 50 pc with CanariCam.
Fainter and more distant disks can be resolved.
We can look for differences in the spectrum of the grains across the disk (e.g. due to the annealing process suggested by Diane Wooden) .
