The direct detection of young and warm extrasolar giant planets in the habitable zone of nearby cool stars is one of the major goals of current ground-based high contrast imaging (HCI) instruments. To characterize such exoplanets by spectroscopy of their atmospheres requires isolating the planet light from the brighter stellar light, which is challenging due to high contrast at small angular separation. Using high performance small inner working angle (IWA) coronagraphs, it is possible to detect faint companions in the proximity of the stellar source. However, the uncontrolled pointing errors and other low-order wavefront aberrations degrade the rejection capability of these coronagraphs by leaking starlight around the coronagraphic focal p...
