Millimeter dust continuum emission unveiling the true mass of giant molecular clouds in the Small Magellanic Cloud
Context. CO observations have been so far the best way to trace molecular gas in external galaxies, but in low metallicity environments the gas mass deduced could be largely underestimated due to enhanced photodissociation of the CO molecule. Large envelopes of H2 could therefore be missed by CO observations. Aims. At present, the kinematic information of CO data cubes are used to estimate viri...
متن کاملExtinction and dust/gas ratio in LMC molecular clouds
Aims. The goal of this paper is to measure the dust content and distribution in the Large Magellanic Cloud (LMC) by comparing extinction maps produced in the near-infrared wavelengths and the spatial distribution of the neutral and molecular gas, as traced by H i and CO observations. Methods. In order to derive an extinction map of the LMC, we have developed a new method to measure the color ex...
متن کاملDust emission in massive star-forming regions with PRONAOS: the Orion and M17 molecular clouds
The balloon-borne submillimeter instrument PRONAOS has observed one square degree areas towards the Orion and M17 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...
متن کاملN ov 2 00 6 Polarization of dust emission in clumpy molecular clouds and cores
Grain alignment theory has reached the stage where quantitative predictions of the degree of alignment and its variations with optical depth are possible. With the goal of studying the effect of clumpiness on the sub-millimeter and far infrared polarization we computed the polarization due to alignment via radiative torques within clumpy models of cores and molecular clouds. Our models were bas...
متن کاملDust Enshrouded Agb Variables in the Lmc
The luminosities and periods of obscured AGB stars in the LMC are discussed using a combination of ISO and ground-based infrared photometry. The bolometric luminosities of these stars fall close to an extrapolation of the period-luminosity relation derived for oxygen-rich Mira variables, with both oxygenand carbon-rich stars falling close to the same relation. It has been known for many years t...
