The EDIBLES Survey. VII. A survey of C2 and C3 in interstellar clouds
Haoyu Fan, Carlos M. R. Rocha, Martin Cordiner +14
We carried out a sensitive survey of C and C using the EDIBLES data set. We also expanded our searches to C, C, and CC isotopologue in the most molecu…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
The EDIBLES survey VI. Searching for time variations of interstellar absorption features
Amin Farhang, Jonathan Smoker, Nick L. J. Cox +10
Interstellar lines observed toward stellar targets change slowly over long timescales, mainly due to the proper motion of the background target relative to the intervening clouds.…
JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs
R. Wesson, Mikako Matsuura, Albert A. Zijlstra +18
We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6m to 25 m. The bright shell is strongly fragmented with som…
Application of the emission model to PAHs and C II.Polycyclic Aromatic Hydrocarbon emission model in photodissociation regions
Ameek Sidhu, A. G. G. M. Tielens, Els Peeters +1
We present a charge distribution-based emission model that calculates the infrared spectrum of fullerenes (C). Analysis of the modelled spectrum of C in various charg…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
