Scientific paper

We present high-spatial-resolution, mid-IR images of young stellar objects (YSO). Images were obtained with MIRAC (Mid-InfraRed Array Camera) at wavelengths of grain continuum and feature emission near 10 and 20µm. Three of the objects observed (WL 16, TY CrA and MWC 1080) show structure and extended emission (on the order of 1200 AU or greater) at wavelengths of the UIR (Unidentified InfraRed) emission features. Mid-IR imaging of other sources in these clouds which do not exhibit UIR features (Elias 29 and R CrA) shows these sources to be point-like. We have produced morphological models based on the mid-IR images for the observed extended structures.
