Scientific paper

We present the first science results from the newly commissioned coronagraphic imaging polarimetry mode of UKIRT's Imager-Spectrometer (UIST). Our pilot science program is designed to begin to trace the evolution of the spatial and size distribution of dust grains in protoplanetary disk systems. The initial observations obtained as part of this program, at H-band, have spatially resolved the scattered light disk associated with a nearby Herbig Ae star. We characterize the morphology of the disk in our H-band coronagraphic imaging polarimetry observations, compare these results to archival optical HST coronagraphic imagery, and discuss the possible origins of morphological structures seen in these data.
