Abstract (from CDS):

We present Antarctic Submillimeter Telescope and Remote Observatory observations of 12CO J=4⟶3 and 12[C I] emission in the 30 Doradus complex in the Large Magellanic Cloud. We detected strong 12CO J=4⟶3 emission toward R140, a multiple system of Wolf-Rayet stars located on the rim of the expanding H II shell surrounding the R136 cluster. We also detected a high-velocity gas component as a separate feature in the 12CO J=4⟶3 spectrum. This component probably originates from molecular material accelerated as a result of the combined motion induced by the stellar winds and explosions of supernovae, including several fast-expanding H II shells in the complex. The lower limit on the total kinetic energy of the atomic and molecular gas component is ∼2x1051 ergs, suggesting that this comprises only 20% of the total kinetic energy contained in the H II complex structure.
