Abstract:
In this
decade we have seen a rapid increase in our understanding of the nature of
extra-solar planetary systems. Space missions such as CoRoT
and Kepler have confirmed that extrasolar planets
are common. The detection of ‘super-Earth’ planets has expanded our planet
inventory towards small, rocky planets. A large diversity of planets became
evident, much wider than found in our Solar System. This diversity raises new
questions to the nature of these planets and their formation and evolution
processes, such as: What is the composition and internal structure of these
planets? What is their atmospheric composition? And for the smallest planets:
are they potentially habitable and how could we detect this? Constraining our
understanding of the underlying processes requires first an improved knowledge
of the basic planet parameters, hence their mean densities, atmospheres and
their age. The talk will give an overview on our knowledge of terrestrial exoplanets and how we will explore their nature with future
space missions, like CHEOPS, TESS and PLATO 2.0.
