The Doppler technique can be used to measure the orbital period of a planet by
A) measuring the time it takes for the star's line-of-sight velocity to cycle from peak to peak.
B) measuring the amount by which the starlight is reduced when the planet transits.
C) measuring the speed at which the star orbits the mutual center-of-mass of the star and planet.
D) measuring the asymmetries in the velocity curve.
