Research Abstract

Though water ice grains are supposed to play many important roles in planet formation processes, observations of water ice in the protoplanetary disk are quite limited so far. We proposed a new observing technique to trace the water ice distribution in the disk and have demonstrated that the water ice grains are present in the disk around HD142527 beyond ～140AU. Unfortunately, we could not continue our observation at Subaru Telescope due to the decommissioning of the adaptive optics system AO36. To proceed with our observations, we made a narrow band filter and installed it to near infrared coronagraphic imager NICI on the Gemini South telescope. We plan to continue observations with this facility to constrain the position of snow line in the protoplanetary disk.
