Photochemical origin of SiC in the circumstellar envelope of carbon-rich AGB stars revealed by ALMA
Yanan Feng, Xiaohu Li, Tom J. Millar +16
Whether SiC is a parent species, that is formed in the photosphere or as a by-product of high-temperature dust formation, or a daughter species, formed in a chemistry driven by…
Complex Organic Molecules Formation in Cold Cores on Stochastically Heated Grains
Long-Fei Chen, Qiang Chang, Yao Wang +1
We investigate the roles of stochastic grain heating in the formation of complex organic molecules (COMs) in cold cores, where COMs have been detected. Two different types of grain…
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…
Three dimensional projection effects on chemistry in a Planck galactic cold clump
J. X. Ge, Diego Mardones, J. H. He +9
Offsets of molecular line emission peaks from continuum peaks are very common but frequently difficult to explain with a single spherical cloud chemical model. We propose that the…
