You observe a face-on binary system(i.E. The plane of the orbits is perpendicular to your line of sight) located 15 pc away. By careful observations, you nd that the orbits are circular with a period of 51 yr., and that the angular separation of the stars to the center of mass are 100 and 1.500, respectively. (a) what are the radii of the orbits of the two stars? (b) what are the orbital velocities of each star? (c)
