two stars, A and B, are in circular orbit of radii r1 and r2, respectively, about their common center of mass. each star has the same period of revolution T.
Determine expressions for the following two quantities in terms of the stars' masses, radii and T.
1- the moment of inertia of the two star system about it's center of mass
2- the angular momentum of the system about teh center of mass
for the moi, i highly doubt it but... would it just be m1r1^2 + m2r2^2 ?
and then to find the angular momentum i can just multiply the I i got before with 2pi/T... ?
thanks. :-)
