HAT-P-7: A RETROGRADE OR POLAR ORBIT, AND A THIRD BODY
We show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86° with respect to its parent star's equatorial plane, and a strong possibility of retrograde motion. We also report evidence for an additional planet or companion star. The evidence for the unpara...
