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…
The s-process at Subsolar Metallicity: Insights from High-Resolution Infrared Spectroscopy of Magellanic Cloud Planetary Nebulae
N. C. Sterling, M. G. Stephenson, Harriet L. Dinerstein +8
We present observations of 12 Magellanic Cloud planetary nebulae (PNe) obtained with the high-resolution near-infrared spectrometer IGRINS on Gemini South. In 10 targets we detect…
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 CO ice in the planetary nebula NGC 6302
Charmi Bhatt, Simon W. Cao, Jan Cami +20
Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…
Detection of CH3+ in the O-rich planetary nebula NGC 6302
Charmi Bhatt, Jan Cami, Els Peeters +33
Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…
