Abstract (from CDS):

We present evidence that the WASP-14 exoplanetary system has misaligned orbital and stellar-rotational axes, with an angle between their sky projections. The evidence is based on spectroscopic observations of the Rossiter-McLaughlin effect as well as new photometric observations. WASP-14 is now the third system known to have a significant spin-orbit misalignment, and all three systems have ``super-Jupiter'' planets (MP > 3MJup) and eccentric orbits. This finding suggests that the migration and subsequent orbital evolution of massive, eccentric exoplanets is somehow different from that of less massive close-in Jupiters, the majority of which have well-aligned orbits.
