Anharmonic Infrared Emission of Cyano-Substituted Polycyclic Aromatic Hydrocarbon Molecules: Cyanonaphthalenes as a Case Study
Tao Chen, Kaijun Li, Aigen Li
Recent detections of cyano-substituted polycyclic aromatic hydrocarbons (cyano-PAHs) highlight them as key tracers of nitrogen heterocycles in the interstellar medium (ISM). Howeve…
Where have all the interstellar silicon carbides gone?
Tao Chen, C. Y. Xiao, Aigen Li +1
The detection of the 11.3-micron emission feature characteristic of the Si--C stretch in carbon-rich evolved stars reveals that silicon carbide (SiC) dust grains are condensed in t…
Fragmentation and isomerization of polycyclic aromatic hydrocarbons in the interstellar medium: coronene as a case study
Tao Chen, Yi Luo, Aigen Li
Aims. Due to the limitations of current computational technology, the fragmentation and isomerization products of vibrationally-excited polycyclic aromatic hydrocarbon (PAH) molecu…
Fully anharmonic infrared cascade spectra of polycyclic aromatic hydrocarbons
Cameron J. Mackie, Tao Chen, Alessandra Candian +2
The infrared (IR) emission of polycyclic aromatic hydrocarbons (PAHs) permeates our universe; astronomers have detected the IR signatures of PAHs around many interstellar objects.…
Failure of hydrogenation in protecting polycyclic aromatic hydrocarbons from fragmentation
Michael Gatchell, Mark H. Stockett, Nathalie de Ruette +13
A recent study of soft X-ray absorption in native and hydrogenated coronene cations, CH , led to the conclusion that additional hydrogen atoms protect (int…
