The Aperture Masking Interferometry mode of NIRISS provides a unique opportunity to probe the close-in (0.1-0.5 arcsec) of extrasolar planetary systems in the thermal infrared regime (3-5 microns). This wavelength coverage will be critical to obtain unbiased estimates of the effective temperature of known directly imaged planets thanks to gravity-insensitive photometric measurements in this regime. The small inner working angle capability of the AMI mode will also be very complementary to ground based AO instruments to search for additional planets behind their blind spots, especially for Sco-Cen systems, a niche of young planetary systems. I will demonstrate this opportunity with applications to the putative multiple system around HD 95086.
