Abstract (from CDS):

We present preliminary results of the ISOCAM survey of the ρ Ophiuchi main cloud L1688 (0.5 square degrees) conducted in the two broad-band filters LW2 (5-8.5µm) and LW3 (12-18µm). This letter focuses on the properties of the extended emission. ISOCAM observations have revealed several previously unknown characteristics of the mid-IR diffuse emission: the small scale filamentary structure (thickness ∼0.03pc) of the emission at the illuminated edge of the molecular cloud, the sharpness of color variations at cloud edges, the barely resolved filamentary structure of the dust emission surrounding a bright embedded source, and several dense cores seen as sharp and deep absorption structures against the diffuse cloud background.
