Production of linear alkanes via the solid-state hydrogenation of interstellar polyynes
G. Fedoseev, X. Li, G. A. Baratta +2
Highly unsaturated carbon chains, including polyynes, have been detected in many astronomical regions and planetary systems. With the success of the QUIJOTE survey of the TMC-1, th…
Ammonium hydrosulfide (NH4SH) as a potentially significant sulfur sink in interstellar ices
Katerina Slavicinska, Adwin Boogert, Åukasz Tychoniec +6
Sulfur is depleted with respect to its cosmic standard abundance in dense star-forming regions. It has been suggested that this depletion is caused by the freeze-out of sulfur on i…
Formation of carbonyl sulfide (OCS) via SH radicals in interstellar CO-rich ice under dense cloud conditions
Julia C. Santos, Harold Linnartz, Ko-Ju Chuang
Carbonyl sulfide (OCS) is widely observed in the gas phase towards star-forming regions and was the first of the only two sulfur-bearing species detected in interstellar ices so fa…
Formation of S-bearing complex organic molecules in interstellar clouds via ice reactions with C2H2, HS, and atomic H
Julia C. Santos, Joan Enrique-Romero, Thanja Lamberts +2
The chemical network governing interstellar sulfur has been the topic of unrelenting discussion for the past decades due to the conspicuous discrepancy between its expected and obs…
Formation of N-bearing complex organic molecules in molecular clouds: Ketenimine, acetonitrile, acetaldimine, and vinylamine via the UV photolysis of CH ice
K. -J. Chuang, C. Jäger, J. C. Santos +1
The solid-state CH chemistry in interstellar HO-rich ice has been proposed to explain astronomically observed complex organic molecules (COMs), including ketene (CH…
