On the left is the image taken by Padgett et al. (1999, ApJ, 117:1490) using the Hubble Space Telescope. These are "pseudo-true color composites" of NICMOS filters at wavelengths 1.1, 1.6, and 2.05 microns. On the right is a true-color image of a preliminary model at the same wavelengths as the NICMOS image. The model consists of a 300 AU radius disk with standard flaring (z ~ r^{9/8}), and a TSC envelope with an infall rate of 5 x 10^{-6} solar masses per yr. A curved bipolar cavity has a small amount of dust in it (Av~0.5). The KMH grains used in this simulation produce very reasonable colors. The intrinsic colors of the central emitting source in the model are those of an average M0 T Tauri star + reprocessing disk, (J-K)0=1.2, (H-K)0=0.43.
With our newly optimized code, we will be able to obtain much better signal-to-noise in the Monte Carlo model. We also observed a jet in this source.
