The relation between far-UV and visible extinctions

Zagury, Frederic

For directions of sufficient reddening ( E( B- V)>∼0.25), there is a simple relation between the slope of the extinction curve in the far-UV and E( B- V). Regardless of direction, the far-UV extinction curve is proportional to 1/ λⁿ e ^{-2 E( B- V)/ λ} ( λ in µm, n=4), in accordance with the idea that reddened stars spe…
