The molecular cloud core M17-North: New ISOCAM observations.

KLEIN R., HENNING T. and CESARSKY D.

Abstract (from CDS):

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 16.6µm 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 M17-North.
