Detection Method: Radial Velocity
The radial velocity method measures slight changes in a star’s velocity as the star and the planet move about their common center of mass. Astronomers can detect these variances by analyzing the spectrum of starlight. In an effect known as Doppler shift, light waves from a star moving toward us are shifted toward the blue end of the spectrum. If the star is moving away, the light waves shift toward the red end of the spectrum. This happens because the waves become compressed when the star is approaching the observer and spread out when the star is receding. The effect is similar to the change in pitch we hear in a train’s whistle as it approaches and passes.
