Scientific paper

We have studied scaling relations (virial mass versus CO luminosity, luminosity versus size, linewidth versus size) for molecular clouds in the 30 Dor and N 159 regions in the Large Magellanic Cloud. The analysis is based on CO J = 1 -> 0 observations with the SEST (Swedish-ESO Submillimeter Telescope). A comparison with corresponding relations for Galactic clouds is made. At this stage of the analysis our conclusions are: (1) 30 Dor, N 159 and Galactic clouds obey the same linewidth-size relation, (2) Virial mass-luminosity and luminosity-size scalings are different in 30 Dor and N 159, but similar in N 159 and the Galaxy, and (3) 30 Dor clouds are less luminous than N 159 and Galactic clouds.
