sYSOm generates emission maps of young stellar objects (YSOs) based on a model composed of a central star, modeled as a blackbody, and a dusty circumstellar disk. The disk is assumed to be geometrically flat with radial-dependent temperature and surface density prescribed by power laws.

The local intensity of the disk, seen at a given inclination, is then given by a blackbody emission at the local temperature weighted by an factor that depends on the local surface density and a chosen dust-opacity model. In addition to images at different wavelengths, sYSOm can also provide the total spectral flux (spectral energy distributions). sYSOm is well suited to model simple YSO objects in the near- and mid-infrared.
