Interstellar Band Absorption in a Supernova?
Nature, 1969THERE is a fairly general consensus of opinion that the interstellar dust consists basically of graphite, with or without various coatings on the grains. In proposing this constitution, Hoyle and Wickramasinghe1 suggested that the grains could be formed in the atmospheres of cool giant stars, in particular the N-type carbon stars.

The Ratio of Total Absorption to Selective Absorption in the Interstellar Space
Publications of the Astronomical Society of Japan, 1968Abstract We have re-examined the value of R, the ratio of the interstellar absorption in V magnitude to the excess in B – V colour, which is one of the parameters showing the properties of interstellar grains. The result is that the ratio R can be taken almost equal to 3.0 for the stars at distances larger than about 1 kpc. The existance

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.

Scattering and Absorption of X-rays by Interstellar Dust
2004In dieser Arbeit habe ich die Eigenschaften der interstellaren Staubpartikel untersucht, wie sie sich aus deren Wechselwirkung mit Roentgen strahlung ergeben. Tatsaechlich werden Photonen, die von einer entfernten Punktquelle stammen, von den Staubteilchen nicht nur absorbiert sondern auch in Vorwaertsrichtung gestreut.

Absorption and Emission Characteristics of Interstellar Dust
1984Molecular transitions which occur in the middle infrared region of the spectrum correspond with the characteristic frequencies of molecular vibrations. Thus, moderate resolution spectroscopy of the interstellar medium offers unique evidence about the molecules in the condensed and gaseous phases and their distribution.
