Abstract (from CDS):

We have mapped the 12CO(1-0) emission from the 30 Doradus region in the Large Magellanic Cloud with the Swedish-ESO Submillimetre Telescope (SEST). The regions investigated include the central part of the 30 Dor nebula, and the southern H II regions N 158C, N 159, and N 160. In addition, a few prominent CO clouds have been studied in the (2-1) and (3-2) transitions of CO. The southern area shows the strongest 12CO(1-0) emission, a factor of 3 higher than towards the central part of 30 Dor. A non-LTE analysis of the CO emission from a sample of clouds indicate kinetic temperatures between 10 and 50 K; the highest temperatures are found close to the 30 Dor nebula. We have estimated the CO-H2 conversion factor for the two areas, separately, under the assumption that the virial mass, determined from CO parameters, reflects the total molecular mass. We find an unexpectedly small difference between the two areas. This is explained as a bias effect.
