Title: Search for exoplanets scultping debris disks with SCExAO+CHARIS
Abstract: Exoplanet imaging is the best way to understand the context and process of wide-orbit, giant planet formation. Three of the five known directly imaged exoplanetary systems harbouring planets within 100 AU of their host stars contain two debris disks based on two temperature SED fits to their IR excess—analogous to our Solar System's Kuiper belt and asteroid belt—with spatially unresolved components modelled interior and exterior to the known planets. This survey requests Subaru SCExAO time to search for other similar two-disk systems in the northern hemisphere, complementary to the ongoing surveys in the south with GPI and SPHERE. An exoplanet detection would help improve our understanding of wide-orbit, giant planet formation as well as the atmospheric physics that causes giant exoplanets to change spectral type as they cool and evolve. Detection of only the debris disk will constrain properties of an unseen planetary system based on the disk’s morphology, such as exoplanet mass, eccentricity, inclination, and multiplicity.
