Binary Stars

  1. Sep 2, 2008 #1
    1. The problem statement, all variables and given/known data

    Centauri A and Centauri B are binary stars with a separation of 3.45x10^12m
    and a period of 2.52x10^9s

    Assuming the two stars are equally massive (which is approximately the case), determine their mass.

    2. Relevant equations

    ( m1 + m2 ) P^2 = ( d1 + d2 )^3 = R^3
    I used this and it doesn't work :x

    3. The attempt at a solution

    M1=M2
    D1=D2

    M(2.52x10^18)=3.45x10^36

    M=3.45x10^36/2.52x10^18

    = wrong :X

    {(2.52 \times 10^9)}^2 \neq 2.52 \times 10^{18}
