At the maximum, the eclipsing variable star has a brightness of 6m, and at a minimum, 8m. Assuming that the eclipse is central and the satellite is dark, find the ratio of the volumes of the components of this pair

The ratio of the brightness of the stars at the maximum and minimum is 2.512 ^ 2 = 6.31. Substituting this number into the formula obtained in solving problem 7.9, we obtain the ratio of the radii of the dark and light components equal to 0.92. The volume ratio of the components will be 0.92, that is, 0.78.
