A Third Star in the HAT-P-7 System and a New Dynamical Pathway to Misaligned Hot Jupiters
The retrograde orbit of the hot Jupiter HAT-P-7b is suggestive of high-eccentricity (high-e) migration caused by dynamical interactions with a massive companion. However, the only other known body in the system is an M dwarf located ∼10 ^3 au away, too distant to cause high-e migration without fine-...
