If a binary system is unresolved into its components then the spectrum obtained from it will actually be a combination of the spectra from each of the component stars. The opening line of any book should say, in the words of Stephen King, “Listen. 1  composed of, relating to, or involving two; dual  2    (Maths, computing)  of, relating to, or expressed in binary notation or binary code  3  (of a compound or molecule) containing atoms of two different elements  4    (Metallurgy)  (of an alloy) consisting of two components or phases ULIRGs classifiedoptically as non-Seyfert galaxies (LINERs, H II regions, andunclassified) are our main targets.
