Question Description:

25.50

Plaskett’s binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below). Assume the orbital speed of each star is || = 200 km/s and the orbital period of each is 14.1 days. Find the mass M of each star in solar masses. (For comparison, the mass of our Sun is 1.99 1030 kg.)

Answer

25.50
