Calculate mass of 2 stars in a binary star system
Suppose that a binary star system consists of two stars of equal mass. They are observed to be separated by 359 million km and to take 4.50 earth years to orbit about a point midway between them. What is the mass of each?

I HOPE THE SEPARATION VALUE IS 359 Mkm, NOT 3.59 Mkm.

The gravitational attractive force between two stars will provide the centripetal force to two stars.
Gravitational force:
Fg = G*m1*m2/(2r)^2
where,
G = universal gravitational constant = 6.67*10^(11) Nm^2/kg^2
m1 = m2 = masses of two ...
