[71.16] Spectral Energy Distributions of Protostars in 2-D Geometries

B. A. Whitney (Space Science Institute), K. Wood (St. Andrews University), J. E. Bjorkman (University of Toledo)

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 \mum 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.
