Dust emission in massive star-forming regions with PRONAOS: the Orion and M 17 molecular clouds
Centre d'Étude Spatiale des Rayonnements - CESR, 9 avenue du Colonel Roche, BP. 4346, 31028 Toulouse Cedex 4, France
The balloon-borne submillimeter instrument PRONAOS has observed one square degree areas towards the Orion and M 17 molecular clouds. The 2'-3.5' resolution maps obtained in four wide wavelength bands between 200 μm and 600 μm, exhibit the dust distribution in these regions. We analyze the temperature and spectral index of the dust, and we show the anticorrelation between these two parameters. We derive estimations of the ISM column densities and masses in these regions.
