ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -XXI. A Large-sample Observational Study of Ethanol and Dimethyl Ether in Hot Cores
Zhiping Kou, Xiaohu Li, Sheng-Li Qin +21
Hot cores, as a stage of massive star formation, exhibit abundant line emissions of COMs. We present a deep line survey of two isomers of CHO: ethanol (CHOH; EA), a…
