Spin-Orbit Angles as a Probe to Orbital Evolution
Abstract
We observed with HARPS, the Rossiter-McLaughlin effect for 40 of the 75 transiting hot Jupiters discovered in the Southern Hemisphere by WASP. Our observations reveal a wide distribution in orbital inclinations indicative of past dynamical interactions. Our data also demonstrate the important effect produced by tidal interactions in shaping the spin-orbit (β) angle distribution. We briefly present and interpret the data we collected in a series of graphs.
