Double Star characteristic frequencies of light

  1. Feb 2, 2004 #1
    How can an astronomer recognize a double star from the characteristic frequencies of the light that reaches him from its member stars? I have looked and looked in my textbook but I cannot come up with the answer to this one.

    Thank you!
