Top left panel (a): Comparison of the UV absorption of indene with an elevated value at λ < 0.19 µm (“higher Cabs”; black long-dashed line) and that with the absorption at λ < 0.19 µm extrapolated from that at λ > 0.19 µm (“lower Cabs”; magenta dashed line). The UV absorption at λ > 0.19 µm for both cases is the same as Figure 1. Bottom left panel (b): Comparison of the MMP83 interstellar radiation field (red) with the radiation fields represented by different stellar effective temperatures (Teff = 40, 000 K: blue; Teff = 22, 000 K: cyan; and Teff = 8, 000 K: green). All the radiation intensities are normalized at λ = 0.2 µm. Right panel (c): Comparison of the model IR emission spectrum of indene in the diffuse ISM calculated with an elevated UV absorption at λ < 0.19 µm (dashed blue line) and that with the extrapolated UV absorption at λ < 0.19 µm (solid red line). -- astro-ph.GA

Infrared Emission of Specific Polycyclic Aromatic Hydrocarbon Molecules: Indene

by Keith CowingMarch 12, 2024March 12, 2024

Polycyclic aromatic hydrocarbon (PAH) molecules have long been suggested to be present in the interstellar medium (ISM). Nevertheless, despite their expected ubiquity and sustained searching efforts, identifying specific interstellar PAH […]
