Description We propose to use Herschel PACS and SPIRE observations to develop a detailed
characterization of the envelope temperature and density structure in
four nearby (d ~ 200-300 pc) protostars. This will enable us to understand how
the non-axisymmetric structure in the surrounding dusty envelopes affects
the infall process and the structure of the inner envelope. The goal of this
proposal is to take advantage of the superb spatial resolution in the far-IR
and sub-millimeter to constrain envelope densities and temperatures over the
wide range of spatial scales involved in protostar formation. The proposed
observations will resolve the warm inner envelope around these protostars
with PACS and map the cold outer envelope with PACS and SPIRE with unparalleled
sensitivity and resolution. The multi-band Herschel data enable us to construct
dust temperature and density maps which we will combine with our existing
Spitzer/near-IR dust extinction maps and measurements of envelope mass and
morphology. We will interpret our observations using radiative transfer models
to provide the most comprehensive characterizations of protostellar envelope
density and temperature structures with which to confront theory.

Mission Description Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
