Abstract
JWST Cycle2 program GO 4332 (PI: S. Vicente) conducts a deep observational study of an EUV+FUV
externally illuminated protoplanetary disk (proplyd) found in the Orion Nebula Cluster (ONC) using
the IFU modes of NIRSpec and MIRI-MRS. The JWST IFU observations spatially resolve the disk, neutral
cocoon and ionization front simultaneously over the 0.9 - 11.7 micron spectral range providing key
line, continuum and PAHs diagnostics to trace the physical conditions, the chemical composition
and abundances under the effect of the external FUV-radiation. It is the FUV radiation that changes
the thermal structure and chemical composition of the disk and sets the mass-loss rate through
photoevaporation. By comparing our results to those of protoplanetary disks (TTauris) found in nearby
low-mass star forming regions one can start to assess the real effects of a FUV-dominant environment
on protoplanetary disk evolution and planet formation. This poster introduces program GO 4332 and
shows preliminary results of the recently acquired MIRI-MRS observations.
