Investigation into broad interstellar absorption lines
Astronomical & Astrophysical Transactions, 2003Diffuse 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, 2018The 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

Variable interstellar absorption lines: a brief review
Astrophysics and Space Science, 2003I review the recent discoveries of variable interstellar absorption lines, widely taken to imply the existence of very small scale(10–100 AU) structure in the interstellar medium. Possible origins of this structure are discussed, and attention is drawn to the fact that most known examples seem to be associated with interstellar shells and bubbles of ...

Absorption Lines from Intermediate-Latitude Interstellar Complexes
Publications of the Astronomical Society of the Pacific, 1966Recent observations of the 21 cm emission line of hydrogen ( Blaauw 1962) have revealed the existence of massive interstellar cloud complexes at considerable distances from the galactic plane. The region 126° < ln < 142°, -19° < bn < -7°, near the association I Persei, in particular, shows a high level of emission at velocities of -48 km/sec (feature ...

Interstellar Emission and Absorption Lines
2012Interstellar emission and absorption lines are discussed, including optical recombination lines, the 21cm hydrogen line, and broad lines such as the interstellar Lyman-alpha line. This chapter ends with a discussion of the curve of growth.

Absorption Line Spectroscopy of the Interstellar Medium
1983Absorption 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.

Determination of distances to interstellar clouds using OH absorption lines
Astrophysics, 1984An attempt is made to determine distances to interstellar clouds by a method free of the limitations of the conventional method (using the galactic rotation curve). It is shown that the term delta, given by the square root of the ratio of the half width of the OH absorption lines to the antenna temperature, varies linearly with the distance R to the ...
