When looking for the radial velocity changes or "wobbles" detected due to Doppler shifts,which mass combination is most likely to be detected?
A) high mass star, high mass planet
B) high mass star, low mass planet
C) low mass star, high mass planet
D) low mass star, low mass planet
E) a high mass planet; the mass of the star is irrelevant

Question

Quizplus · Accepted Answer

A low mass star with a high mass planet is most likely to be detected because the gravitational influence of the planet causes a more noticeable wobble in the star's motion, making the Doppler shifts easier to detect.
