Singly- and doubly-deuterated formaldehyde in massive star-forming regions
S. Zahorecz, I. Jimenez-Serra, L. Testi +5
Deuterated molecules are good tracers of the evolutionary stage of star-forming cores. During the star formation process, deuterated molecules are expected to be enhanced in cold,…
Physical Conditions in the LMC's Quiescent Molecular Ridge: Fitting Non-LTE Models to CO Emission
Molly K. Finn, Remy Indebetouw, Kelsey E. Johnson +8
The Molecular Ridge in the LMC extends several kiloparsecs south from 30 Doradus, and it contains ~30% of the molecular gas in the entire galaxy. However, the southern end of the M…
