Presentation #606.05 in the session Stellar Spins and Obliquities.
Transiting giant planets provide a natural opportunity to examine stellar obliquities. Hot Jupiters orbiting Sun-like stars show a tendency for obliquity alignment, which suggests that obliquities are rarely excited or that tidal realignment is common. However, the stellar obliquity distribution is less clear for giant planets at wider separations where realignment mechanisms are not expected to operate. I will present results of the underlying inclination distributions among 47 cool stars harboring hot and warm Jupiters using hierarchical Bayesian modeling. We find that the inferred minimum misalignment distributions of hot Jupiters spanning a/R = 3-20 ( ~0.01-0.1 AU) and warm Jupiters spanning a/R = 20-400 ( ~0.1-1.9 AU) are mutually consistent. Most cool stars hosting warm and hot Jupiters are consistent with spin-orbit alignment. However, the similarity of misalignment rates suggests that either misalignments are primordial, or both misaligned hot and warm Jupiters experience the same underlying processes.
