MUSE Imaging Spectroscopy of the Fullerene Planetary Nebula Tc 1
J. R. Walsh, M. J. Barlow, A. Monreal-Ibero +6
The planetary nebula Tc 1 (PN G345.2 -08.8), one of the rare group of Galactic PNe showing fullerene emission in the infrared, was observed with MUSE wide field mode with adaptive…
Searching for the elusive CH2+ with the James Webb Space Telescope. Another carbocation to constrain astrochemical networks
M. Zannese, L. H. Coudert, E. Dartois +14
Carbocations are key species in interstellar chemistry, providing entry points for building larger hydrocarbons. CH+, and more recently, CH3+, have been detected. Other carbocation…
Discovery of a TiO emission band in the infrared spectrum of the S star NP Aurigae
K. Smolders, T. Verhoelst, P. Neyskens +10
We report on the discovery of an infrared emission band in the Spitzer spectrum of the S-type AGB star NP Aurigae that is caused by TiO molecules in the circumstellar environment.…
PDRs4All XV: CH radical and H molecular ion in the irradiated protoplanetary disk d203-506
I. Schroetter, O. Berné, J. R. Goicoechea +20
Most protoplanetary disks experience a phase in which they are subjected to strong ultraviolet radiation from nearby massive stars. This UV radiation can substantially alter their…
The Rotational Excitation Temperature of the 6614 Diffuse Interstellar Band Carrier
J. Cami, F. Salama, J. Jiménez-Vicente +2
Analysis of high spectral resolution observations of the 6614 diffuse interstellar band (DIB) line profile show systematic variations in the positions of the peaks in the subst…
Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
G. C. Sloan, K. E. Kraemer, B. Aringer +9
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significan…
