ABSTRACT: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{ mu m} 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.
Based on observations with ISO, an ESA project with
instruments funded by ESA Member States (especially the PI countries: France,
Germany, the Netherlands and the United Kingdom) with the participation of ISAS
and NASA.
