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…
JWST observations of the Ring Nebula (NGC 6720) -- II. PAH emission
Nicholas Clark, Els Peeters, Nick L. J. Cox +16
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in clumpy circumstellar environments, yet their formation and evolutionary pathways in such environ…
PDRs4All XVI. Tracing aromatic infrared band characteristics in photodissociation region spectra with PAHFIT in the JWST era
Dries Van De Putte, Els Peeters, Karl D. Gordon +13
Photodissociation regions (PDRs) exhibit emission between 3-20 um known as the Aromatic Infrared Bands (AIBs), originating from small carbonaceous species such as polycyclic aromat…
JWST: Deuterated PAHs, PAH-nitriles, and PAH Overtone and Combination Bands I: Program Description and First Look
C. Boersma, L. J. Allamandola, V. J. Esposito +6
A first look is taken at the NIRSpec 1-5 m observations from JWST program 1591 that targets 7 objects along the low-mass stellar life cycle with PAH emission. Spectra extracted…
PAHs and star formation in the HII regions of nearby galaxies M83 and M33
A. Maragkoudakis, N. Ivkovich, E. Peeters +3
We present mid-infrared (MIR) spectra of HII regions within star-forming galaxies M83 and M33. Their emission features are compared with Galactic and extragalactic HII regions, HII…
A Dust Twin of Cas A: Cool Dust and 21-micron Silicate Dust Feature in the Supernova Remnant G54.1+0.3
J. Rho, H. L. Gomez, A. Boogert +4
We present infrared (IR) and submillimeter observations of the Crab-like supernova remnant (SNR) G54.1+0.3 including 350 micron (SHARC-II), 870 micron (LABOCA), 70, 100, 160, 250,…
Probing the Ionization States of Polycyclic Aromatic Hydrocarbons via the 15-20 μm Emission Bands
M. J. Shannon, D. J. Stock, E. Peeters
We report new correlations between ratios of band intensities of the 15-20 μm emission bands of polycyclic aromatic hydrocarbons (PAHs) in a sample of fifty-seven sources observed…
Characterizing the infrared spectra of small, neutral, fully dehydrogenated PAHs
C. J. Mackie, E. Peeters, C. W. Bauschlicher +1
We present the results of a computational study to investigate the infrared spectroscopic properties of a large number of polycyclic aromatic hydrocarbon (PAH) molecules and their…
The mid-infrared appearance of the Galactic Mini-Starburst W49A
D. J. Stock, E. Peeters, W. D. -Y. Choi +1
The massive star forming region W49A represents one of the largest complexes of massive star formation present in the Milky Way and contains at least fifty young massive stars stil…
Carbon-rich dust past the asymptotic giant branch: aliphatics, aromatics, and fullerenes in the Magellanic Clouds
G. C. Sloan, E. Lagadec, A. A. Zijlstra +10
Infrared spectra of carbon-rich objects which have evolved off the asymptotic giant branch reveal a range of dust properties, including fullerenes, polycyclic aromatic hydrocarbons…
On the Excitation and Formation of Circumstellar Fullerenes
J. Bernard-Salas, J. Cami, E. Peeters +3
We compare and analyze the Spitzer mid-infrared spectrum of three fullerene-rich planetary nebulae in the Milky Way and the Magellanic Clouds; Tc1, SMP SMC16, and SMP LMC56. The th…
Unusual Dust Emission from Planetary Nebulae in the Magellanic Clouds
J. Bernard-Salas, E. Peeters, G. C. Sloan +5
We present a Spitzer Space Telescope spectroscopic study of a sample of 25 planetary nebulae in the Magellanic Clouds. The low-resolution modules are used to analyze the dust featu…
