Title: Probing the inner gap of a newly imaged debris disk

Abstract: HIP 79977 is a young ( 5-10 Myr) star in Upper Scorpius with an infrared excess implying the existence of a debris disk with an inner gap at 40 AU. We recently imaged this disk for the first time with Subaru/HiCIAO, using angular differential imaging (ADI). The images show hints of an inner gap, but a larger field rotation is required for accurately mapping this region of the disk with ADI, which requires a telescope in the Southern hemisphere due to the declination of the target. Here, we propose to use NICI for this purpose. The observations would give a better sense of the disk morphology and may reveal planetary companions in the system, if the gap is dynamically cleared.
