Which of these methods for detecting exoplanets is MOST analogous to the pulsar timing method?
A) transit method
B) microlensing
C) distorted protoplanetary disk
D) radial velocity method

Question

Quizplus · Accepted Answer

The pulsar timing method and the radial velocity method both involve detecting periodic changes in the motion of a star (or pulsar) due to the gravitational influence of orbiting planets. In the pulsar timing method, variations in the timing of pulsar emissions are observed, while in the radial velocity method, changes in the star's velocity along our line of sight, indicated by shifts in spectral lines, are measured. Both methods rely on the gravitational effects of planets on their host stars to infer the presence of these planets.
