A 12-year time-lapse sequence of telescope images captures a star with four orbiting exoplanets, revealing their orbital motion over more than a decade. The long-baseline imaging provides rare observational data on multi-planet system dynamics through direct imaging rather than indirect detection methods.
Background
Direct imaging of exoplanets is one of the most challenging observational techniques, requiring advanced coronagraphs and adaptive optics. Long-term monitoring of directly imaged planetary systems provides critical data on orbital parameters and system architecture.
