Tracking Solar Supergranulation: How the Sun’s Surface Patterns Evolve Over Its Magnetic Cycle

This study tracks how the Sun’s supergranulation, a surface flow pattern, varies over its magnetic cycle and impacts exoplanet detection. Using HARPS-N data and two correction methods, the authors found that supergranulation timescales are longest during solar minimum. They also show that observing strategies must account for this variability to improve planet-hunting precision, both for the Sun and other stars.
