The Law of Interstellar Reddening and Absorption.
Abstract
The law of interstellar reddening and the slope of the reddening lines in the plot of U - B versus B - V have been reinvestigated in the light of more extensive data. The data consist of a catalogue of 262 0 stars for which we have three-color photometry and slit spectrograms. The anomalous behavior of stars in the Great Rift in Cygnus found by Johnson and Morgan is confirmed. The equation of the mean reddening line is E(U-B) -0.72+ 0.05E(B-v). E(B-v) A rediscussion of the ratio of total to selective absorption, with additional new data, gives R = Av - 3.0 + 0.2 (p.e.). E(B-v)
