We report high-resolution spectroscopy of the moderately reddened (AV = 3) early-type star Cernis 52 located in a region of the Perseus molecular cloud complex with anomalous microwave emission. In addition to the presence of the most common diffuse interstellar bands (DIBs) we detect two new interstellar or circumstellar bands coincident to within 0.01% in wavelength with the two strongest bands of the naphthalene cation (C10H8+) as measured in gas-phase laboratory spectroscopy at low…

Context. The identification of the carriers of the diffuse interstellar bands (DIBs) is the longest standing problem in the study of the interstellar medium. Here we present recent UV laboratory
Identification of H2CCC as a diffuse interstellar band carrier
We present strong evidence that the broad, diffuse interstellar bands (DIBs) at 4881 and 5450 Å are caused by the B1B1 ← X1A1 transition of H2CCC (l-C3H2). The large widths of the bands are due to

Search for corannulene (C20H10) in the Red Rectangle
Polycyclic Aromatic Hydrocarbons (PAHs) are widely accepted as the carriers of the Aromatic Infrared Bands (AIBs), but an unambiguous identification of any specific interstellar PAH is still missing.
Interstellar naphthalene cations (C10H+8) have been proposed by a study to be the carriers of a small number of diffuse interstellar bands (DIBs). Using an archive of high signal-to-noise spectra

A painstaking comparison of laboratory gas-phase spectra of the naphthalene cation with an extensive set of astrophysical spectra was carried out. In the vicinity of both naphthalene features, found

A recent laboratory study of ionized napthalene (C10H8(+)) has led to the suggestion that some of the unidentified diffuse interstellar bands may be formed by this molecular ion in the diffuse

The Diffuse Interstellar Bands
The diffuse interstellar bands are absorption features observed in the spectra of stars seen through significant column densities of interstellar material. Of the 127 confirmed DIBs in the optical
