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…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs
R. Wesson, Mikako Matsuura, Albert A. Zijlstra +18
We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6m to 25 m. The bright shell is strongly fragmented with som…
Polycyclic Aromatic Hydrocarbon Size Tracers
A. Maragkoudakis, E. Peeters, A. Ricca +1
We examine the dependence of polycyclic aromatic hydrocarbon (PAH) band intensity ratios as a function of the average number of carbon atoms and assess their effectiveness as trace…
Application of the emission model to PAHs and C II.Polycyclic Aromatic Hydrocarbon emission model in photodissociation regions
Ameek Sidhu, A. G. G. M. Tielens, Els Peeters +1
We present a charge distribution-based emission model that calculates the infrared spectrum of fullerenes (C). Analysis of the modelled spectrum of C in various charg…
Spectral variations among different scenarios of PAH processing or formation
A. Maragkoudakis, E. Peeters, A. Ricca
We examine the variations in the spectral characteristics and intensities of PAHs in two different scenarios of PAH processing (or formation): (1) small PAHs are being destroyed (o…
