Exoplanet observations: On the road to finding our place in the Galaxy — •Hans-Jörg Deeg — Instituto de Astrofísica de Canarias, Tenerife, Spain

An overview will be given over the development of exoplanet detection and characterization, which have shown us a large and unexpected variety of planetary systems. The radial velocity and the transit methods have been responsible for the vast majority of currently known planet systems. Furthermore, they are often used jointly on the same target, leading to the best-characterised planets and planet systems. Currently the most detailed knowledge on some planets is derived from spectroscopic observations during transits, of which some examples are being shown. These observations require large ground-based facilities and are among the principal drivers for instrument development on the next generation of very large telescopes. Lastly, on overview over upcoming exoplanet related space missions will be given, mainly the American TESS mission, currently scheduled for launch on March 20, 2018, and the European PLATO mission, set for launch in 2026. Both of these missions should provide a huge sample of planet detections on bright targets. Comparative exoplanetology based on statistical analyses of larger samples may then be expected to become a central field in the research on exoplanets. We may then also finally be able to put our solar system into context with our galactic neighbourhood.
