Diffuse interstellar bands

Astronomical & Astrophysical Transactions, 2003
The identification of diffuse interstellar bands (DIBs) remains an open problem since discovery of the first two such features 80 years ago. Any attempt to solve the mystery of the carrier(s) of the DIBs must involve interdisciplinary collaboration between molecular physicists, chemists and astronomers.

Diffuse interstellar absorption bands

Science in China Series G: Physics, Mechanics and Astronomy, 2009
The diffuse interstellar bands (DIBs) are a large number of absorption bands that are superposed on the interstellar extinction curve and are of interstellar origin. Since the discovery of the first two DIBs in the 1920s, the exact nature of DIBs still remains unclear.

Diffuse interstellar bands

Publications of the Astronomical Society of the Pacific, 1988
The paper presents a review of the observational investigations of the diffuse interstellar bands (DIBs) which, despite being the object of considerable research, remain unidentified since 1921. The review is focused on the most recent investigations done with the aid of solid-state detectors which make it possible to obtain high S/N spectra.

On the diffuse interstellar bands

Journal of the Chemical Society, Faraday Transactions, 1993
The problem of the diffuse interstellar bands is considered from a spectroscopic viewpoint. A partial decomposition of the astrophysical spectrum based on the grouping of some of the bands into families is discussed with particular reference to ‘diffuse bands’ observed in emission from the Red Rectangle nebula.

The Diffuse Interstellar Band Spectrum

1995
The location of diffuse interstellar bands (DIBs) in the electromagnetic spectrum, their shape and relative position, as well as their relative intensities contain information about the nature of the DIB carrier. What follows is a brief summary of such features of the DIB spectrum as they emerge from a recent systematic survey of DIBs and from related ...

Shape of the Diffuse Interstellar Bands

Nature Physical Science, 1971
THE diffuse interstellar bands, which have been known for about 36 years1, are still one of the mysteries of astronomy. One hope has been that with definite identification of these bands will come not only further information about interstellar matter and its condition but, more specifically, more information about the nature of interstellar grains ...

Disclosing Identities in Diffuse Interstellar Bands

Science, 2011
The linear isomer of C 3 H 2 has been proposed as the source of broad absorption bands in diffuse interstellar clouds, but it is still being debated.

The Diffuse Interstellar Bands and Interstellar Dust

1995
As far as we now know, interstellar dust and the diffuse interstellar bands (DIBs) are not directly related; there is no really good correlation between any DIB and a specific feature of interstellar extinction. I argue that it is not useful to consider the λ2175 “bump”, by far the strongest feature in the interstellar extinction law (in terms of ...

The Diffuse Interstellar Bands: A Tracer For Organics In The Diffuse Interstellar Medium?

Origins of life and evolution of the biosphere, 1998
The diffuse interstellar bands (DIBs) are absorption bands seen in the spectra of stars obscured by interstellar dust. DIBs are recognized as a tracer for free, organic molecules in the diffuse interstellar medium (ISM). The potential molecular carriers for the DIBs are discussed with an emphasis on neutral and ionized polycyclic aromatic hydrocarbons (

Observations of diffuse interstellar bands and of interstellar polarization

Planetary and Space Science, 1995
Abstract Results are presented from two distinct observational projects, concerning the optical diffuse interstellar bands observed with high-resolution and ultra-high resolution spectroscopy. and UV interstellar polarization observed with the Hubble Space Telescope.
