Abstract

While the timing method was the first to successfully detect exoplanets, the radial velocity method has quickly developed as a standard method for exoplanet detection. The timing method has received more interest in recent years due to two different areas of exoplanet reserach. On the one hand, eclipse time variations have shown that planets exist in exotic environments like in post common envelope binaries. This raises the questions whether or not these planets have survived the significant mass loss of the binary system or if there is a second phase of planet formation. On the other hand, the transit timing variation offers the possibility to detect and confirm exoplanets from photometric data alone. With the large number of multi-transiting planetary systems the Kepler satellite detected, this method can now be applied to several systems. In the talk, I summarize our contributions to the eclipse time and transit timing method.
