| الوصف: | High-contrast optical stellar interferometry generally refers to instruments able to detect circumstellar emission at least a few hundred times fainter than the host star at high-angular resolution (typically within a few \lambda/D). While such contrast levels have been enabled by classical modal-filltered interferometric instruments such asVLTI/PIONIER, CHARA/FLUOR, and CHARA/MIRC the development of instruments able to fi lter out the stellar light has signi cantly pushed this limit, either by nulling interferometry for on-axis observations (e.g., PFN, LBTI, GLINT) or by o -axis classical interferometry with VLTI/GRAVITY. Achieving such high contrastlevels at small angular separation was made possible thanks to signi cant developments in technology (e.g., adaptive optics, integrated optics), data acquisition (e.g., fringe tracking, phase chopping), and data reduction techniques (e.g., nulling self-calibration). In this paper, we review the current status of high-contrast optical stellar interferometry and present its key scienti c results. We then present ongoing activities to improve current ground-based interferometric facilities for high-contrast imaging (e.g., Hi-5/VIKING/BIFROST of the ASGARD instrument suite, GRAVITY+) and the scienti c milestones that they would be able to achieve. Finally, wediscuss the long-term future of high-contrast stellar interferometry and, in particular, ambitious science cases that would be enabled by space interferometry (e.g., LIFE, space-PFI) and large-scale ground-based projects (PFI). |
