Chemical models of interstellar glycine and adenine precursor aminoacetonitrile (NH2CH2CN)
Xia Zhang, Donghui Quan, Xiaohu Li +4
Aminoacetonitrile (AAN), also known as glycinenitrile, has been suggested as a possible precursor of glycine and adenine in the interstellar medium. Here we present the chemical mo…
Tentative detection of cyanoformamide NCCONH2 in space
Juan Li, Donghui Quan, Junzhi Wang +12
The peptide-like molecules, cyanoformamide (NCCONH2), is the cyano (CN) derivative of formamide (NH2CHO). It is known to play a role in the synthesis of nucleic acid precursors und…
Chemical models of adenine precursors cyanamide and carbodiimide in the interstellar medium
Xia Zhang, Donghui Quan, Runxia Li +4
Cyanamide (NH2CN) and its isomer, carbodiimide (HNCNH), may form adenine in the interstellar medium (ISM) via a series of reactions. Therefore, they are considered key prebiotic mo…
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…
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…
