High-resolution mid-infrared observations of very young stellar objects in NGC 1333.

Abstract (from CDS):

We observed 22 young stellar objects in the region of NGC 1333 by using the mid-infrared camera MIRLIN. NGC 1333 (in the Perseus OB2 molecular cloud complex) is a relatively well studied region, but not at high spatial resolution in the mid-infrared. MIRLIN's 0".5 spatial resolution allows us to look for source extension and multiplicity and to place new constraints on spectral energy distributions. We report here new detections of eight objects at mid-IR wavelengths. We find one object, SVS 12, that may be extended or multiple, and we confirm multiplicity in SVS 16. We find a new companion to ASR 107. We are able to classify six objects as Class I, flat spectrum, or II, place strong classification constraints on two objects, and more loosely restrict the classification of eight more objects. These observations will aid in interpretation of planned SIRTF observations of this cluster.
