Paper Abstract

As the push for a dedicated direct exoplanet imaging mission intensifies, and numerous mission concepts are drafted and refined, a growing concern has been that not enough attention has been paid to the effects of exozodiacal light. As most mission simulations have assumed uniform or smoothly varying exozodi levels, there exists a danger that a potential future planet imager will be unable to succeed in its mission due to 'clumped' exozodi. We have used our existing framework for evaluating the capabilities of direct planet imagers to simulate the effects of non-uniform exozodi on mission outcomes, including modeling the increased integration time that may be required, and the possibility of increased false positives.
