Scientific paper

Recent HST observations have provided the best resolved images of young circumstellar disks yet seen. In several cases, of which HH 30 is the best known example, nebulous young stars are resolved by HST into bipolar reflection nebulae several hundred AU in extent separated by a central dark absorption lane obscuring direct view of the star. Modeling suggests that these systems are edge-on optically thick circumstellar disks which occult the radiation from the star and near- stellar disk environment out to far-IR wavelengths. We propose a snapshot survey of nearby nebulous young stellar objects to study the detailed morphology of the their disks and envelopes and probe the effect of inclination on the infrared spectral energy distribution of disk/envelope systems.
