Definition. Created. Interstellar dust absorbs more blue light than red light, making stars appear redder than their true color. The reddening of an object is inversely proportional to the wavelength of optical light , so shorter wavelengths (blue) are more heavily reddened than longer (red) wavelengths. → reddening…

It is Definition of the noun Reddening. In astronomy, interstellar reddening is a phenomenon associated with interstellar extinction where the spectrum of electromagnetic radiation from a radiation source changes characteristics from that which the object originally emitted.

What is interstellar reddening?
Dust scatters blue light In fact, studies have shown that the extinction and reddening are related by: A V =3.2E(B-V) So if we know what the reddening is, we can calculate the extinction and correct our magnitude equation.

( plural space reddenings) (astronomy) The reddening of the light from distant stars because of selective absorption and scattering by interstellar dust. reddening definition: Verb 1. For an A0-type main sequence star (these have median wavelength and heat among the main sequence) the color indices are calibrated at 0 based on an intrinsic reading of such a star (± exactly 0.02 depending on which spectral point, i.e. Reddening the snowy streets with the prevailing Republican colour, in winding and tramping through them, as they had reddened them below the snow with a deeper dye, they carried him thus into the courtyard of the building where he lived.
