Differential Rotation of CoRoT Stars and a Kepler Binary Star from Starspot Transit Mapping

Valio, Adriana; Araújo, Alexandre; Menezes, Fabian

While direct magnetic field measurements are rare for slowly rotating stars, spots observed during planetary transits provide a potential indicator of magnetic activity on stellar surfaces. Moreover, the rotation of the stellar surface can be probed by monitoring the spots' position with time in subsequent transits. This study investigates the dyn…
