The Rossiter-McLaughlin effect for exoplanets

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

There are now more than 35 stars with transiting planets for which the stellar obliquity-or more precisely its sky projection-has been measured, via the eponymous effect of Rossiter and McLaughlin. The history of these measurements is intriguing. For 8 years a case was gradually building that the orbits of hot Jupiters are always well-aligned with the rotation of their parent stars. Then in a sudden reversal, many misaligned systems were found, and it now seems that even retrograde systems are not uncommon. I review the measurement technique underlying these discoveries, the patterns that have emerged from the data, and the implications for theories of planet formation and migration.
