Prospects for polarimetry, exozodiacal, and debris disk observations with the Roman Space Telescope coronagraph instrument


The Roman Coronagraph will be able to perform high-contrast scattered light observations of extended sources in intensity and measure their linear polarization fraction per resolution element. We will summarize the concept of operations for polarimetric observations, illustrate the sensitivity to debris disks, and summarize prospects for a highly-sensitive survey of scattered light from exozodiacal disks as a precursor to future high-contrast missions.
