Measuring the angle between an exoplanet’s orbit and its host star’s spin can provide clues regarding the formation and evolution of exoplanetary systems, in particular hot Jupiters. The Rossiter-McLaughlin effect and Doppler Tomography are complementary methods that use established techniques to measure this angle. Between these two methods, the spin-orbit alignment of more than 100 exoplanetary systems has been measured, leading to interesting insights into planetary migration and tidal interactions.

I’ll give a quick overview of the Rossiter-McLaughlin effect and Doppler Tomography for those unfamiliar with the technique, show some recent results obtained with these methods, and look at new developments that may lead to major changes in the field.
