Predicted Colors And Spectral Energy Distributions Of Young Stars In The Herschel Pacs And Spire Filters.
Abstract
The Herschel Space Observatory, the most sensitive far-IR/sub-mm observatory to date, is expected to revolutionize our view of the earliest phases of star formation. Upcoming surveys with Herschel's PACS and SPIRE instruments will yield far-IR photometry of large samples of young stellar objects associated with molecular clouds. We present theoretical predictions for the colors and luminosities of protostellar envelopes and protoplanetary disks in the passbands of the PACS and SPIRE instruments. These predictions are based on a grid of model calculations using the code of Whitney et al. (2003, ApJ, 591, 1049). From these predictions, we will assess what properties of protostars can be constrained from the Herschel photometry by itself and combined with mid-IR photometry from Spitzer surveys. We will also discuss uncertainties in the models and how these may affect the predicted fluxes.
