Rossiter-McLaughlin Effect

(effect of transit on visible spectrum of the star)

The Rossiter-McLaughlin Effect is the hiding of some of the relatively red- or blue-shifted light from a rotating star by a transiting Extra Solar Planet or binary companion. Study of the spectroscopic changes show characteristics of the orbit such as whether it is retrograde to the star's rotation.
