interstellar extinction in a sentence

Examples

1. Sometimes the emission feature in the core of the K line is affected by the interstellar extinction.
2. Broadly speaking, interstellar extinction is strongest at short wavelengths, generally observed by using techniques from spectroscopy.
3. It is highly reddened and Interstellar extinction causes it to be 6.5 magnitudes fainter at visual wavelengths.
4. KY Cygni is heavily reddened due to interstellar extinction, losing an estimate 7.75 magnitudes at visual wavelengths.
5. Of apparent magnitude 5.59, its brightness is dimmer by 0.05 magnitude due to interstellar extinction.
6. IUE data was used to show that within the galaxy, interstellar extinction can be well described by a few simple equations.
7. Struve was one of the first astronomers to identify the effects of interstellar extinction ( though he provided no mechanism to explain the effect ).
8. It is also necessary to know the amount of interstellar extinction to the cluster and this can be difficult in regions such as the Carina Nebula.
9. This was explained by the interstellar dust scattered through the galaxy, resulting in the absorption ( extinction ) of light or interstellar extinction of light.
10. Almost all astronomical observations are affected by this interstellar extinction, and correcting for it is the first step in most analyses of astronomical spectra and images.
