The Young Ages of 70 μm Dark Clumps Inferred from Carbon Chain Chemistry
The physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules HC _5 N, CCS, and HC _7 N in the 22–25 GHz band toward 12 high-mass 70 μ m dark clumps (SMDC) with the Karl G. Jansky Ve...
