INVESTIGATION OF DIFFUSE INTERSTELLAR BANDS OF ORGANIC MOLECULES IN THE SPECTRA OF CEPHEID STARS
Odessa Astronomical Publications, 2016 We describe an effective method of investigation of the Diffuse Interstellar Bands (DIBs) in the spectra of Cepheid stars. DIBs are believed to originate from the absorption of such carriers as polycyclic aromatic hydrocarbons in the interstellar gaseous

Diffuse Interstellar Bands – The Unidentified Part of the Interstellar Absorption Spectrum [PDF]
Symposium - International Astronomical Union, 1989 The unidentified (since 1921) diffuse interstellar bands (DIBs) are discussed together with their relations to other interstellar absorptions sucn as: continuous extinction, polarization and atomic or molecular absorption lines. It is shown that DIBs do not form the absorption spectrum of one agent, but probably of several (3 or more).

Interstellar Matter Structure along the Line of Sight to Cyg X-1
Open Astronomy, 2015 High-resolution spectra (R = 60 000) of Cyg X-1 = V1357 Cyg obtained with the NES echelle spectrograph of the Russian 6 meter telescope (3950–6690 Å) were used to study narrow interstellar absorption lines.

Interstellar Absorption of Some Be Stars [PDF]
International Astronomical Union Colloquium, 1987 It is well known that the intrinsic colors of Be stars are not the same as those of “normal” B stars and they are often redder. So interstellar absorption of Be stars determined from photometric indices may be overestimated. In order to avoid this, a method often used to determine the interstellar absorption of Be stars is based on the ultraviolet ...
