We report the measurement of a spin-orbit misalignment for WASP-79b, a
recently discovered, bloated transiting hot Jupiter from the WASP survey. Data
were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous
calibration system feeding the UCLES spectrograph on the Anglo-Australian
Telescope. We have used the Rossiter-McLaughlin effect to determine the
sky-projected spin-orbit angle to be lambda = -106+19-13 degrees. This result
indicates a significant misalignment between the spin axis of the host star and
the orbital plane of the planet -- the planet being in a nearly polar orbit.
WASP-79 is consistent with other stars that have Teff > 6250K and host hot
Jupiters in spin-orbit misalignment.Comment: 8 pages, 2 figures, in press ApJL (accepted 2 August 2013
