Finding and chaRActerizing forMing Exoplanets – FRAME

Submission summary

High contrast imaging techniques are just starting to provide the first images of forming planets nested within the circumstellar disks surrounding young stars. These discoveries offer to dramatically refine our knowledge of the formation and phases of early dynamical evolution of planetary systems. The characterization of the gas accretion processes onto these planets can also remove critical uncertainties of planet evolution and planet migration models. We proposes a full incursion in the nascent field of protoplanet detection and characterization. FRAME will determine the physics involve during the planet accretion phase inspiring from the characterization strategies used on protostars. We will also develop specific data processing techniques to boost the detection of forming planets at shorter angular separations (10-100 au) in datacubes produced by medium and high-resolution spectrographs.
