Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying the…
The Computed Microwave Spectrum of the Protonated Fullerene C60H+
Laszlo Nemes, Jos Oomens, Vincent J. Esposito +2
The largest known molecule in space, C60 , has been detected in its neutral and cationic form through its vibrational, UV-driven fluorescence emission spectrum and its electronic a…
Aromatic Species in the Molecular Universe
A. G. G. M. Tielens
Interstellar polycyclic aromatic hydrocarbon (PAHs) are an important component of the interstellar medium of galaxies, containing some 10 percent of the elemental carbon. Their vib…
PDRs4All: XVIII. The evolution of the PAH ionisation and PAH size distribution across the Orion Bar
Alexandros Maragkoudakis, Christiaan Boersma, Els Peeters +25
We investigate the evolution of the PAH population's charge state and size across key physical zones in the Orion Bar, which include the HII region, the atomic PDR (APDR), and thre…
PDRs4All VI: Probing the Photochemical Evolution of PAHs in the Orion Bar Using Machine Learning Techniques
S. Pasquini, E. Peeters, B. Schefter +21
[Abridged] JWST observations of the Orion Bar have shown the incredible richness of PAH bands and their variation on small scales. We aim to probe the photochemical evolution of PA…
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…
Photoinduced polycyclic aromatic hydrocarbon dehydrogenation: The competition between H- and H2-loss
P. Castellanos, A. Candian, J. Zhen +2
PAHs constitute a major component of the interstellar medium carbon budget, locking up to 10--20% of the elemental carbon. Sequential fragmentation induced by energetic photons lea…
