We present 2-D radiative equilibrium models of pre-main sequence stars at various evolutionary states. The inclusion of bipolar cavities and flared disks in the geometries of embedded protostars has a significant effect on the resultant spectral energy distributions. When results from several models are combined into color-color plots, inclination effects cause large overlap between regions thought to represent different evolutionary states (e.g., young pole-on sources are bluer than older edge-on sources). Our color-color plots span the wavelength range from 1-160 μ m centered on the standard near-IR (JHK) and SIRTF (IRAC and MIPS) wavebands. Images at these wavelengths are also presented and displayed to expected SIRTF sensitivities. This work was supported by the National Science Foundation (AST-9909966, AST-9819928) and NASA (NAG5-8587, NAG5-8794).
