Mass of stars

  1. Feb 25, 2009 #1
    Suppose that a binary-star system consists of two stars of equal mass. They are observed to be separated by 350 million {\rm km} and take 5.4 Earth years to orbit about a point midway between them.

    I got 1.1x10^29 as my answer, but it is incorrect. Can anyone help me out?

    You're looking for the orbital relationship for a two body rotating about themselves.

    Do you have that equation in the book you are studying?
