The Doppler technique can be used to estimate the semimajor axis of a planet's orbit by
A) measuring the asymmetries in the velocity curve.
B) measuring the time it takes for the star's line-of-sight velocity to cycle from peak to peak, and using Newton's version of Kepler's Third law.
C) measuring the speed at which the star orbits the mutual center-of-mass of the star and planet, and using Newton's theory of gravity.
D) measuring the amount by which the starlight is reduced when the planet transits.
