The JWST Proto-PAH project: Aromatic backbones with extensive aliphatic substitution account for both the aromatic and aliphatic emission
N. Clark, E. Peeters, J. Cami +18
We find that the aromatic and aliphatic emission bands in four carbon-rich post-asymptotic giant branch stars with class D emission arise from a single carrier population: extensiv…
The JWST Proto-PAH project. Computational modeling of the emission carriers
A. Ricca, G. C. Sloan, E. Peeters +8
The infrared spectra of many carbon-rich post-asymptotic giant branch stars are dominated by emission features from aromatic and aliphatic hydrocarbons, but the chemical structure…
The JWST Proto-PAH Project: Detection of the methyl radical CH in the highly evolved C-rich object SMP LMC 011
Jialu Li, D. A. García-Hernández, A. Manchado +17
We report the first detection of the neutral methyl radical CH in a highly evolved C-rich object, SMP LMC 011, using JWST MIRI/MRS. CH is well fitted by an excitation tempe…
Detection of unidentified molecular pure rotational lines in C-rich PNe I. The fullerene-containing PN IC 418
T. Huertas-Roldán, J. P. Fonfría, J. Alcolea +7
Molecular emission is observed in a wide variety of astrophysical environments, yet a substantial fraction of spectral features detected at mm wavelengths remains unidentified. Ide…
Stellar nucleosynthesis in the era of large surveys: S-process polluted binaries in GALAH DR4
A. Escorza, S. Vitali, D. Godoy-Rivera +11
Binary interactions during the AGB phase can lead to the formation of chemically peculiar stars with overabundances of s-process elements. Only a few hundreds of these stars have b…
Peculiarities in the infrared emission of PAH-C adducts
R. Barzaga, B. Kerkeni, D. A. García-Hernández +7
The coexistence of PAHs and the C fullerene in different astrophysical environments can give rise to the formation of new complex species denoted as PAH-C adducts, wh…
Hydrogenated amorphous carbon grains as an alternative carrier of the 913m plateau feature in the fullerene planetary nebula Tc 1
M. A. Gómez-Muñoz, D. A. García-Hernández, R. Barzaga +2
Fullerenes have been observed in several astronomical objects since the discovery of C in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc 1. It has been s…
