Plaskett€™s binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This means that the masses of the two star are equal (Fig. P13.13). Assume the orbital speed of each star is 220 km/s and the orbital period of each is 14.4 days. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 # 1030 kg.)
