The applet design by prof Hwang modified layout by Ahmed.
Original applet Circular double stars

Assume the mass for stars are M,m.
The density is assume to be the same for both stars, so the radius for M will change when M is changed.
The distance between star is d,

The radius for the circular motion are r and d-r,
where $M\, r=(d-r)\,m$ , and $\frac{GMm}{d^2}=M\,r w^2=m(d-r) w^2$

The black dot is the center of mass (CM) for the binary stars ststem.
