The Shape of the Interstellar Reddening Curve [PDF]
International Astronomical Union Colloquium, 1965 When the Observed Spectral Intensity Distribution of an early-type star has been freed from the distortions caused by absorption in the Earth's atmosphere and by instrumental sensitivity factors, it is a measure of the true spectral intensity distribution of the star and of the modifications to that distribution caused by the interstellar material ...

On one special feature of the interstellar reddening lines [PDF]
, 1988 Показано, что линии межзвездного покраснения имеют сложную структуру. Обсуждается возможность связи такой структуры с различиями химического состава звезд.It is shown that the interstellar reddening lines are of a complex structure.

The Correlation of Interstellar Reddening and Lα Absorption [PDF]
Symposium - International Astronomical Union, 1973 For 61 stars whose interstellar Lα absorption was observed by OAO-2, the average relation of H I column density to B – V color excess is equal to 5 × 1021 atoms cm–2 mag–1. For a recent dust grain model this value implies that the density ratio 〈ρHI/ρdust〉 ≈ 100.

The Astrophysical Journal, 2023 Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength-dependent variations seen in Milky Way extinction are strongly correlated with the single parameter R ( V ) = A ( V )/ E ( B − V )

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way
The Astrophysical Journal, 2022 Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

Turbulence in the interstellar medium [PDF]
, 2014 Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Luminosity class of the symbiotic stars 4U1954+319 and ZZ CMi [PDF]
Serbian Astronomical JournalWe performed optical photometry and spectral observations of the symbiotic stars 4U1954+319 and ZZ CMi. For 4U1954+319, using high-resolution spectra, we, measure the equivalent widths of diffuse interstellar bands (DIBs) and estimate the interstellar ...
