Effect of surface H on molecular hydrogen formation on interstellar grains
Gang Zhao, Qiang Chang, Xia Zhang +3
We investigate how the existence of hydrogen molecules on grain surfaces may affect H formation efficiency in diffuse and translucent clouds. Hydrogen molecules are able to red…
Chemical variations across the TMC-1 boundary: molecular tracers from translucent phase to dense phase
Long-Fei Chen, Di Li, Donghui Quan +4
We investigated the chemical evolutions of gas phase and grain surface species across the Taurus molecular cloud-1 (TMC-1) filament from translucent phase to dense phase. By compar…
On the Encounter Desorption of Hydrogen Atoms on Ice Mantle
Qiang Chang, Xuli Zheng, Xia Zhang +5
At low temperatures (10 K), hydrogen atoms can diffuse quickly on grain ice mantles and frequently encounter hydrogen molecules, which cover a notable fraction of grain surface. Th…
Mapping Observations of complex organic molecules around Sagittarius B2 with ARO 12m telescope
Juan Li, Junzhi Wang, Haihua Qiao +10
We performed high-sensitivity mapping observations of several complex organic molecules around Sagittarius B2 with ARO 12m telescope at 3-mm wavelength. Based on their spatial dist…
Spatial Variation of the Chemical Properties of Massive Star-forming Clumps
Mingyue Li, Jianjun Zhou, Jarken Esimbek +4
We selected 90 massive star-forming clumps with strong N2H+, HCO+, HCN, and HNC emission from the Millimetre Astronomy Legacy Team 90 GHz survey. We obtained Herschel data for all…
