PDS 70 is the only current young disk system with directly imaged companions linking dust traps/filtration to companions. We propose SCExAO/CHARIS spectropolarimetric observations of two young protoplanetary disk systems, V1247 Ori and V1366 Ori, that exhibit similar evidence of dust filtration and dust trapping as seen in PDS 70. The new discovery space enabled by CHARIS’ exquisite inner working angle, its new polarimetry mode, and its pristine extreme-AO performance will enable us to test two key predictions in these systems. First, aim to provide the first detection and characterization of the 50 MJup substellar companion at 0.1" that is predicted to be responsible for sculpting the inner disk of the V1366 Ori system. Second, we aim to robustly detect the disk wall in V1247 Ori that is predicted to be skewing the astrometry of a planet suggested in the system from sparse aperture interferometric observations. For both targets, our observations will also enable additional novel tests relevant to the study of young planet-forming systems – such as constraining dust properties and composition or testing the possible drivers of spiral structures.
