Coverage Dependent H Desorption Energy: a Quantitative Explanation Based on Encounter Desorption Mechanism
Qingkuan Meng, Qiang Chang, Gang Zhao +5
Recent experiments show that the desorption energy of H on a diamond-like carbon (DLC) surface depends on the H coverage of the surface. We aim to quantitatively explain th…
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…
