Exoplanets@SAC: 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. We also determine similar quantities in double star systems, measurements which serve as ground truth. I will explain our techniques and present some recent highlights.
