Searching for the elusive CH2+ with the James Webb Space Telescope. Another carbocation to constrain astrochemical networks

M. Zannese, L. H. Coudert, E. Dartois +14

Carbocations are key species in interstellar chemistry, providing entry points for building larger hydrocarbons. CH+, and more recently, CH3+, have been detected. Other carbocation…

PDRs4All XV: CH radical and H molecular ion in the irradiated protoplanetary disk d203-506

I. Schroetter, O. Berné, J. R. Goicoechea +20

Most protoplanetary disks experience a phase in which they are subjected to strong ultraviolet radiation from nearby massive stars. This UV radiation can substantially alter their…

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…

PDRs4All XI. Detection of infrared CH and CH rovibrational emission in the Orion Bar and disk d203-506: evidence of chemical pumping

Marion Zannese, Benoît Tabone, Emilie Habart +20

The methylidyne cation (CH) and the methyl cation (CH) are building blocks of organic molecules, yet their coupled formation and excitation mechanisms remain mainly unpro…

Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk

Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53

Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
