In the context of the forthcoming giant telescopes, accessible probed resolutions will soon be greatly upgraded, unveiling the innermost regions of stellar systems. It is reasonable to wonder to what extent the science in young stellar systems will benefit from these revolutionizing facilities, particularly regarding the detection of forming exoplanets or the characterization of their host discs.

To address this question, I performed full radiative transfer simulations of a typical young stellar system using the MCFOST code. The model consists in a young Sun-like star surrounded by a face-on disc in which a gap is carved by a planet. I built realistic synthetic observations of this model using coronagraphic image sequences of the instrument MICADO/MORFEO. I reduced these observations using the RDI or ADI techniques in the Near-InfraRed J, H and K bands.

From there, I derived detection limits of the MICADO/MORFEO for embedded planets and their corresponding gap structures as a function of the planet parameters. I showed that the environing disc material significantly complicates the detection of embedded planets, and that the gap structure triggered by Jupiter-like planet could be detectable.
