We present Atacama Large (sub)Millimeter Array observations of 30 Doradus—the highest resolution view of molecular gas in an extragalactic star formation region to date (∼0.4 pc × 0.6 pc). The 30Dor-10 cloud north of R136 was mapped in 12CO 2–1, 13CO 2–1, C18O 2–1, 1.3 mm continuum, the H30α recombination line, and two H2CO 3–2 transitions. Most 12CO emission is associated with small filaments and clumps (≲1 pc, ∼103 M☉ at the current resolution). Some clumps are associated with protostars… 
Structural and Dynamical Analysis of 0.1 pc Cores and Filaments in the 30 Doradus-10 Giant Molecular Cloud
High-resolution (<0.1 pc) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the 30Dor-10 molecular cloud 15 pc north of R136 are presented. The 12CO 2–1 emission morphology contains
