Abstract

Exoplanet research has entered an era, where the stability, sensitivity, and accuracy of our instruments and spacecrafts would allow the detection of Earth’s twin. Inhomogeneities on stellar surfaces cause temporal changes in the observed signals, which cannot only mimic, but completely hide any signal that is caused by a planet. However, we can turn this problem around and use planetary transits to understand those surface inhomogeneities. 

I will present current physics based modeling efforts in understanding solar and stellar surfaces and their imprints in data used for exoplanet research, as well as efforts in observational campaigns, which provide insights on stellar activity and the surfaces themselves.
