Ammonium salt formation and abundance in protoplanetary disks
Maxime Ruaud, Jean-Christophe Loison, Uma Gorti
Ammonium salts may represent an important reservoir of volatile species in Solar system primitive bodies, but the question of how and when these salts can form during the star form…
Kinetic and H-atom product study of the C + C6H6 reaction at low temperatures
Kevin M. Hickson, Jean-Christophe Loison
The reactions of atomic carbon in its ground electronic state configuration, C(3P), are potentially important processes in astrochemistry due to the large abundance of C(3P) atoms…
The Reaction between Atomic Carbon and Molecular Nitrogen as a Source of Cyanamide and Carbodiimide on Interstellar Ices
Kevin M. Hickson, Jean-Christophe Loison, Audrey Coutens
Reactions occurring on the ice-covered surfaces of interstellar dust grains are considered to be among the most important sources of complex species in the interstellar medium. Des…
Evidence for Phenylium Reactivity under Interstellar Relevant Conditions
Jean-Christophe Loison, Corentin Rossi, Nicolas Solem +4
Recent work by Kocheril \textit{et al.}\cite{kocheril2025} claimed that phenylium--the cyclic structure of the \ce{C6H5+} species--is unreactive toward key interstellar molecules s…
Discovery of linear propadienone: Study of the chemistry of linear and cyclic HCO and HCS in TMC-1
G. Esplugues, J. C. Loison, M. Agúndez +4
We report the first detection in space of propadienone, the linear isomer (l-HCO) of cyclopropenone (c-HCO). We also report the first detection of the isotopologue…
A Gas-Phase Kinetic Study of the N(2D) + CH3CCH and N(2D) + CH3CN Reactions
Kevin M. Hickson, Jean-Christophe Loison, Benjamin Benne +1
The chemistry of planetary atmospheres containing molecular nitrogen as a major atmospheric component is strongly influenced by the reactions of atomic nitrogen. Although nitrogen…
