Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection [PDF]

Astronomy & Astrophysics, 2013
We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found.

Diffuse interstellar bands in M33 [PDF]

Proceedings of the International Astronomical Union, 2013
We present the first sample of diffuse interstellar bands (DIBs) in the nearby galaxy M33. Studying DIBs in other galaxies allows the behaviour of the carriers to be examined under interstellar conditions which can be quite different from those of the ...

Mapping The Interstellar Medium With Near-Infrared Diffuse Interstellar Bands [PDF]

The Astrophysical Journal, 2015
We map the distribution and properties of the Milky Way's interstellar medium as traced by diffuse interstellar bands (DIBs) detected in near-infrared stellar spectra from the SDSS-III/APOGEE survey.

Linear/circular spectropolarimetry of diffuse interstellar bands [PDF]

Astronomy & Astrophysics, 2011
Context. The identification of the carriers of diffuse interstellar bands (DIBs) remains one of the long-standing mysteries in astronomy. The detection of a polarisation signal in a DIB profile can be used to distinguish between a dust or gas-phase ...

Detection of diffuse interstellar bands in M31 [PDF]

Astronomy & Astrophysics, 2008
We investigate the diffuse interstellar band (DIB) spectrum in the interstellar medium of M31. The DEIMOS spectrograph of the W. M. Keck observatory was used to make optical spectroscopic observations of two supergiant stars, MAG 63885 and MAG 70817, in ...

Laboratory infrared spectra and fragmentation chemistry of sulfur allotropes [PDF]

Nature Communications
Sulfur is one of six life-essential elements, but its path from interstellar clouds to planets and their atmospheres is not well known. Astronomical observations in dense clouds have so far been able to trace only 1 percent of cosmic sulfur, in the form ...

First Principles Rovibronic Absorption Spectra of HF Molecule. [PDF]

J Comput Chem
Hydrogen fluoride (HF) is astrophysically important, as it has been detected in sunspots, Venus, red giants, and the interstellar medium, serving as a probe of exoplanet atmospheres. This article presents an ab initio investigation of HF rovibronic spectroscopy, combining high‐level electronic‐structure data with nuclear‐motion solutions and refinement

Mid-infrared Spectroscopy of Protonated Benzonitrile, 2-Cyanonaphthalene, and 9-Cyanoanthracene for Astrochemical Consideration. [PDF]

Chemphyschem
Experimental infrared absorption spectra of three protonated cyano‐substituted PAHs measured by infrared multiple photon dissociation using the free‐electron laser Free‐Electron Laser for Infrared eXperiments are studied. These spectra are compared to an emission spectrum measured by JWST, and the largest measured protonated cyano‐PAH, cyanoanthracene,

Mapping local interstellar medium with diffuse interstellar bands [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT With the use of the data from archives, we studied the correlations between the equivalent widths of four diffuse interstellar bands (4430, 5780, 5797, 6284 $\mathring{\rm A}$) and properties of the target stars (colour excess values, distances, and Galactic coordinates).

Diffuse Interstellar Bands [PDF]

Symposium - International Astronomical Union, 2000
The unidentified diffuse interstellar bands are observed in near-UV, visible and near-IR spectra recorded towards stars which are partially obscured by interstellar dust. Their origin is the longest standing problem in astronomical spectroscopy and dates back to the 1930s when systematic study of the bands first started.
