Abstract

We measured the spin-orbit misalignment for WASP-79b, a transiting hot Jupiter from the WASP survey. Using the Rossiter-McLaughlin effect during the transit event, we determined the sky-projected obliquity to be λ = -106+10-8°. This result indicates that the planet is in a nearly polar orbit.
