CH radio emission from heiles cloud 2 as a tracer of molecular cloud evolution
N. Sakai, H. Maezawa, T. Sakai +2
A mapping observation of the -type doubling transition (3.3 GHz) of CH has been conducted toward Heiles Cloud 2 (HCL2) in the Taurus molecular cloud complex to reveal it…

DNC/HNC Ratio of Massive Clumps in Early Evolutionary Stages of High-Mass Star Formation
Takeshi Sakai, Nami Sakai, Kenji Furuya +3
We have observed the HN13C J=1-0 and DNC J=1-0 lines toward 18 massive clumps, including infrared dark clouds (IRDCs) and high-mass protostellar objects (HMPOs), by using the Nobey…
