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 stars are equal. Assume the orbital speed of each star is 180 km/s and the orbital period of each is 12. 4 days. Find the mass M of each star in units of "solar masses." (One solar mass is 1. 99 :13 1030 kg.)
