Tomofumi Umemoto,Takahiro Iwata,Yasuo Fukui,Hitomi Mikami,Satoshi Yamamoto,Osamu Kameya,Naomi Hirano +6 more
TL;DR: In this paper, a well-collimated bipolar CO outflow associated with a cold IRAS source 20386+6751 has been discovered in the L1157 dark cloud, and the gas kinetic temperature toward the blue lobe of the outflow rises to-30 K from the temperature of the surrounding gas (≤10 K).
