Summary
Exoplanetology has become a major topic in astronomy over the last 30 years. New observing capabilities and
modelling have revolutionised the understanding of how planetary systems form and evolve. Yet, the 5-20 au
region, where the giant planets formed by accretion of gas on to a solid core are supposed to form predominantly,
remains barely explored due to instrumental limitations. GAIA and the E-ELT instruments will be well suited to
explore planetary systems at this scale. However, I believe that exploring this region is possible right now, at a
small cost, with the use of recent innovative signal processing developments applied to current High Contrast
Imaging (HCI) data and/or the use of high-performance, AO-fed medium/high resolution spectrographs.
With COBREX, I want to apply such new data processing techniques on the largest library of SPHERE and GPI
HCI data to gain at least one order of magnitude (hence a gain of ~3 in mass/separation) on current planet and disk
detection limits in the 5-20 au region. This will allow witnessing, for the first time, analogues of our Solar System
Giants at early ages, and constraining the distribution of GPs in the 5-20 au. Combining in different ways various
data (HCI, GAIA, RV) will allow exploring the demography of young giant planets at all separations. Then, I want
to couple HCI with medium/high resolution spectroscopy, to find and study planet properties into exquisite details,
and investigate in an unprecedented way the link between disks and planets. Finally, I wish to explore the possibility
of imaging remote magmatic super-Earths in the near future thanks to such improvements.
