When looking for the "Doppler Wobble" (radial velocity changes detected due to Doppler shifts), which mass combination is most likely to be detected?

Question

Quizplus · Accepted Answer

The most likely mass combination to be detected using the Doppler Wobble technique is a low mass star with a high mass planet. This is because the gravitational influence of the planet on the star is stronger than the star's influence on the planet due to the star's lower mass. This causes the star to wobble with a larger amplitude, making it easier to detect with the Doppler Wobble technique. High mass planets would also cause a larger wobble, but high mass stars are less common and have shorter lifetimes, making it less likely to find a high mass star with a detectable wobble.
