What did we find out?<br />
• When the <strong>stars</strong> are farther apart (a is increased) they<br />
move more slowly in their orbit.<br />
• Measuring the time it takes for the spectral lines to<br />
return to their starting wavelength gives us the orbital<br />
period<br />
• When the mass <strong>of</strong> one star is increased the other star<br />
orbits at a greater distance.
