Scientific paper

We will obtain mid-IR spectra of two deeply embedded Class I protostars in the Lynds 1634 bright-rimmed cloud. These sources drive two outflows. With IRAC and MIPS data (both 24 and 70) already in hand and combined with extant submillimeter fluxes for both sources (Beltran et al. 2002), this is among the most complete high resolution and sensitive data set for protostars in the mid-IR. Using these data we will construct detailed models for these very young sources. The IRS spectra will be essential for understanding the roles of silicates and ices in the protostellar envelope, information that can not be accurately inferred from the broad band fluxes alone. We will compare the central source properties derived from the models with dynamical calculations for the outflows based on existing millimeter-wave molecular line maps (DeVries 2003).
