The discovery of giant planets orbiting close to their host stars was one ofthe most unexpected results of early exoplanetary science. Astronomers havesince found that a significant fraction of these 'Hot Jupiters' move on orbitssubstantially misaligned with the rotation axis of their host star. We recentlyreported the measurement of the spin-orbit misalignment for WASP-79b by usingdata from the 3.9 m Anglo-Australian Telescope. Contemporary models ofplanetary formation produce planets on nearly coplanar orbits with respect totheir host star's equator. We discuss the mechanisms which could drive planetsinto spin-orbit misalignment. The most commonly proposed being the Kozaimechanism, which requires the presence of a distant, massive companion to thestar-planet system. We therefore describe a volume-limited direct-imagingsurvey of Hot Jupiter systems with measured spin-orbit angles, to search forthe presence of stellar companions and test the Kozai hypothesis.
