A Detailed Analysis of Intermediate-scale Structure in Optical Extinction Curves: Expanded Census and Two-family Classification

C. M. Gunasekera, M. Decleir, K. D. Gordon +4

The features of interstellar extinction curves serve as powerful diagnostics for interstellar dust, revealing information about its composition, size distribution, and the physical…

Detection of C $_{60}$ 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 $I^¼$ m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…

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…
