Abstract: Imaging exoplanets provides unique insights to our knowledge about planet formation and evolution. However this is an extremely challenging task: the angular separation between the star and the planet is of a few hundred milli-arcseconds and the brightness ratio is of a few billion. To tackle this, a very specific instrument is needed but still the images we obtain are corrupted by the so-called “speckle noise” within which planets are hidden. Adapted post-processing is therefore necessary to unveil the planets in the images. The current post-processing techniques used have limitations that we need to address to image more exoplanets but also the environment in which they evolve to, in the end, understand better our universe.
