Scientific paper

We present a grid of near-IR model images of pre-main sequence stars at different stages of evolution. The grid encompasses over 150 models, a large subset of which will be available on a website currently in development. The models demonstrate the effects of varying disk size, outflow cavity shape, inclination, and infall rate on the colors and morphology of a young stellar object. We show that several features in the models can be used to constrain estimates of the disk size and the evolutionary state of observed pre-main sequence stars. We use our models to interpret HST NICMOS observations of young stellar objects in Taurus (Padgett et al, 1999). This work was supported by The Hubble Space Telescope (HST-AR-08367.01-97A) and NASA's LTSA program (NAG5-8933).
