Scientific paper

Results are presented on millimeter and submillimeter continuum observations of six FU Orionis stars and one possible pre-FU Orionis star. The measured submillimeter and mm continuum was combined with mid-IR and far-IR observations to model the source of thermal emission in these sources. Results suggest that the disks around FU Orionis are active, not passive, and that the material in the disks may be accretionally unevolved. It is suggested that the FU Orionis stars may be young T Tauri stars.
