Tentative identification of the diffuse interstellar absorption bands and of a diffuse interstellar doublet line

Astrophysics and Space Science, 1969
The four diffuse interstellar absorption bands at λ4430, λ4760, λ4890, and λ6180 and the two diffuse lines at λ5780 and λ5797 are interpreted as belonging to pre-ionization transitions in H− and O−, respectively. In both cases the identifications are supported by extrapolations of wave numbers of resonance lines along isoelectronic sequences.

Absorption Line Spectroscopy of the Interstellar Medium

, 1983
Absorption line studies of the interstellar medium are described. The discussion is in three parts. The first describes current views of diffuse interstellar clouds, while the second reports the results of recent extensive surveys of interstellar regions. The final part is an outline of possible future observations.

Investigation into broad interstellar absorption lines

Astronomical & Astrophysical Transactions, 2003
Diffuse interstellar bands (DIBs) are investigated mainly with high-resolution spectroscopy, which allows very fine structures to be detected. However, the rapidly increasing resolution of echelle spectra becomes a disadvantage when broad absorption structures are involved.

Variable interstellar absorption lines in young stellar aggregates

Monthly Notices of the Royal Astronomical Society, 2018
The variability of interstellar atomic lines, sporadically reported in the astronomical literature, has been confirmed both in the case of the nearby hot star delta Ori and the very young and violent star-forming region eta Carinae, using high-resolution echelle spectra. The presented variability concerns the intensities and profiles of Na I, KI and Ca
