A mapping survey of massive CO cores

We mapped 21 star-forming regions with the 12CO, 13CO and C18O (1−0) lines using the 13.7-m telescope of Purple Mount Observatory. This mapping survey resolved 53 13CO cores, of which 22 are sourceless. We obtained the physical parameters of these cores. The relation between 13CO linewidth and core...
