Orbital Orientations of Exoplanets: Hat-p-4b is Prograde and Hat-p-14b is Retrograde

Orbital Orientations of Exoplanets: Hat-p-4b is Prograde and Hat-p-14b is Retrograde

We present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent stars. HAT-P-4b is prograde, with a sky-projected spin-orbit angle of λ = –4.9 ± 11.9 deg. In contrast, HAT-P-14b is retrog...
