Characterizing the dusty disks around the wide-orbit planetary-mass companions may provide new insight into satellite formation around giant planets. While considerable effort has been devoted at millimeter wavelengths, imaging warm dust is much more favorable in the mid-infrared regime. The 6.5-meter James Webb Space Telescope (JWST) will soon start its Cycle 1 observations in late 2022 and directly probe the dimension, structure, and grain composition of these elusive disks. Here we present the motivation, technical design, and the expected results of our approved JWST Cycle 1 survey with the MIRI imager.
