Two stars in a binary system, are seen edge-on from Earth. The HB line emitted by Star 1 varies between 486.162 nm and 486.186 nm, while that emitted by Star 2 varies between 486.140 nm and 486.208 nm. Assuming the stars are on a circular orbit, calculate the orbital velocity of the two stars and their mass ratio. What additional observational data is required to
