SUMMARY
Stellar jitter is significantly influenced by convective motions within the stellar photosphere, as detailed on page 26 of the document from Queen Mary University of London. These convective currents create vertical movements that affect the radial velocity detection methods, which utilize Doppler shifts to measure the motion of stars caused by orbiting planets. The variability in these currents can introduce noise and uncertainty in Doppler shift measurements, leading to inaccurate assessments of stellar motion.
