TL;DR: The Kepler mission was designed to determine the frequency of Earth-sized planets in and near the habitable zone of Sun-like stars, which is the region where planetary temperatures are suitable for water to exist on a planet's surface.

TL;DR: In this article, the Rossiter-McLaughlin (R-M) effect of a transiting planet identified by the NASA Kepler mission was detected. But the R-M effect was not used to confirm the existence of the planet.
