Many observations became understandable only when astronomers realized that there are huge clouds of gas and dust in interstellar space, by which the light of far-off stars is dimmed and reddened. In order to reduce our observations for this effect, we have to find how this extinction depends on wavelength; our results will also help to understand the ...

Interstellar Extinction and Diffuse Absorption Features

Astrophysics and Space Science, 1975
The equivalent width of the λ 2175 A band, W 2175, well known as the big bump in the interstellar extinction curves, has been found to be closely correlated with the colour excess E B-V as well as with the extinction differences E 8−6 and E 8−6 defined to characterize quantitatively the steep slopes of the extinction curves in the far ultraviolet.

Features of the interstellar extinction curve

Astrophysics and Space Science, 1975
The extinction curves for spherical particles are subject to the errors of the particle material’s refractive index. Their sensitivity to these errors has been investigated and is found to be dependent upon wavelength. For graphite, significant errors are produced in the far ultraviolet part of the extinction curve; for silicates, in the near ...
