Derived from Kepler’s Third Law.
Unfortunately, we do not know the inclination angle.
Might be found with optical spectroscopy (see if binary edge on).
Get lower limit on masses.
Light curve – if secondary eclipses, get sine wave.
Tells you actual rotation rate of secondary.
We have vsini.
Light curves give v.
-> get i
