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…

Infrared spectral signatures of light r-process elements in kilonovae

Anders Jerkstrand, Quentin Pognan, Smaranika Banerjee +8

A central question regarding neutron star mergers is whether they are able to produce all the r-process elements, from first to third peak. The high abundances of first-peak elemen…

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…

The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation

Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34

NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
