The molecular cloud core M 17-North: New ISOCAM observations
نویسنده
چکیده
We present spectro-imaging data of the molecular cloud core M17-North. The data have been obtained with the ISOCAM camera on board of the Infrared Space Observatory (ISO) using the circular variable filters (CVF). The spectra have a spectral resolution of about 40. They are dominated by PAH emission bands. A band at 16.6 μm is detected which is ascribed to the family of the PAH bands. Further, the PAH bands display clearly Lorentzian line profiles. The observations led to the detection of a new mid-infrared source with a very strongly rising continuum. The observed spatial distribution of fine structure line emission of neon and argon ions is a sign for an ionizing source in M 17-North.

ISOCAM mapping of the Ophiuchi main cloud
We present preliminary results of the ISOCAM survey of the Ophiuchi main cloud L1688 (0.5 square degrees) conducted in the two broad-band filters LW2 (5-8.5 m) and LW3 (12-18 m). 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 (thickn...
متن کاملInfrared spectrophotometry of M 17 with ISOCAM
We report spectrophotometric observations of the H ii region/neutral medium interface in M 17 obtained with the ISOCAM Circular Variable Filter (CVF) in the spectral range 5.15 to 16.5 m. The lines of singly–ionized species come mainly from the clumpy "neutral" interface, while the H ii region dominates the line emission by higher–ionization species. The emission in the Unidentified Infrared Ba...
متن کاملInfrared spectrophotometry of NGC 7023 with ISOCAM
We present spectrophotometric observations of the reflection nebula NGC 7023 obtained with the ISOCAM Circular Variable Filter (CVF) in the spectral range 5.15 to 16.5 m. Maps in the 16 m continuum emission and in the Unidentified Infrared Bands (UIBs) have been obtained. The continuum emission peaks at the dense interface between the surrounding molecular cloud and the inner photodissociated r...
متن کاملMid-IR mapping of the region of N 4 in the Large Magellanic Cloud with ISOCAM
We present images of the N 4 region in the Large Magellanic Cloud obtained with ISOCAM on board ISO through broad band filters centered at 6.75 and 15 μm. Far from the three H ii regions contained in the map, the emission at both wavelengths is due to the Unidentified Infrared Bands and associated continuum and originates in the external layers of a molecular cloud complex. The ratio between th...

We present the first complete infrared spectrum of a molecular cloud core covering the wavelength region from 2.4 up to 200 μm together with a map at 1.3 mm wavelength and near-infrared (NIR) images. The core is located in the northern part of M 17 and shows strong evidence for on-going star formation. These data are the first step towards a complete characterization of M 17-North. The spectrum...
