Abstract
The infrared spectral energy distributions (SEDs) of circumstellar transitional disks reveal the presence of an optically thin inner region and an optically thick outer disk. As a class they are relatively rare, and only the brightest are suitable for resolving disk structure. Only a few transitional disks have been studied on the scales necessary to resolve the central cavity. We present here Submillimeter Array (SMA) observations of the continuum emission from the disk around RXJ1633.9-2242, which we previously established as an excellent candidate to harbor forming giant planets as suggested by its low mass accretion rate, the relatively massive disk, and the SED morphology. We have also performed a radiative transfer modeling of the SED and derived a set of best fitting properties for the disk.
