 note = {SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, Icy grains are supposed to play various important and critical roles on planet formation, though observational understanding of the ice distribution is quite limited so far. With the SPICA observations of ice and its distribution in the various disks, we can make a significant progress on our understanding of the icy grain distribution in the disk. In instruments proposed for SPICA, especially the SCI has big potential for tracing the distribution of the icy grain directly thanks to the function of the coroangraphic spectroscopy. The aims of the direct observations with the SCI are (1) to establish the existence of the water ice in the debris disk, (2) to measure spatial distribution of ice grain, and (3) to challenge to trace the “snow line”, for the first time. Combined observations of SAFARI (aiming for 44 μm water ice feature) and SCI (aiming for 3, 6.2 μm water ice feature) will be especially effective for establishing the presence/non-presence of water ice grain in the debris disks., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027077, レポート番号: JAXA-SP-17-010E},
