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: 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 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…
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…
WEAVE imaging spectroscopy of NGC 6720: an iron bar in the Ring
R. Wesson, J. E. Drew, M. J. Barlow +23
We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE, a new instrument m…
Planetary Nebula Evolution for Single Stellar Models. The Formation of Neutral Spikes
Guillermo Garcia-Segura, Arturo Manchado, Jesus A. Toala +2
Two-dimensional hydrodynamical simulations are presented from the formation up to the late evolution of planetary nebula, for 6 different stellar models from 1 to 5 Mo. The hydrody…
