Abstract:	We present a mid-J CO emission line study of the largest HII complex, the 30 Doradus nebula in the Large Magellanic Cloud (LMC). This is the most luminous example of a starburst region in the Local Group. We have searched for 12CO J = 7 → 6 emission towards the 30 Doradus complex with the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO), located at 2847 m above mean sea level at the Amundsen-Scott South Pole Station. As a result we have detected a 12CO J = 7 → 6 emitting cloud near the 30 Doradus complex. The 12CO J = 7 → 6/12CO J = 4 → 3 line temperature ratio in this region is approximately a factor of two higher than that observed near the Sgr B2 complex. A radiative transfer calculation using the line ratios shows that the core of massive star formation in the LMC is much warmer and denser than that of the Milky Way region.
