Exoplanets@IFA: System architectures of exoplanet systems
Over the last twenty years astronomers have discovered thousands of planets orbiting other stars than our sun. Many of these exoplanets display characteristics very different from the planets in our own solar system. Among these are planets on very eccentric (highly elliptical) and highly inclined (oblique) orbits. At Aarhus University one of our research foci is on getting a better understanding of these characteristics by measuring the system architectures for systems ranging from hot-Jupiters to systems with small multiple planets. I will explain our techniques and present some recent highlights. We also started studying planets showing Transit Timing Variations (TTV). Here we focus on systems which had not been fully characterized by the Kepler mission due to Kepler's limited life time. These systems we now continue to monitor using ground based telescopes.
