Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, The zodiacal light (ZL) is the dominant diffuse radiation in the mid-infrared wavelengths from the interplanetary dust. Although the zodiacal dust cloud has a relatively smooth distribution, it has many small-scale structures, such as asteroidal dust bands and a circumsolar resonance ring. A number of models for the zodiacal dust cloud have been developed, in particular, using the infrared satellite data, such as IRAS and COBE/DIRBE, thus far. Although the DIRBE ZL model (e.g. Kelsall et al. 1998) reproduces the observed infrared sky well, there are still uncertainties in the model parameters. Since IRAS, COBE/DIRBE, and AKARI were the sun-synchronous orbit satellites, they observed the infrared sky through the circumsolar ring in the Earth’s orbit. SPICA will be launched onto a halo orbit around L2 point, which is 0.01 AU away from the Earth. In this orbit, we may be able to observe the small-scale structures more clearly. The asteroidal dust bands contribute to the ZL brightness most in the 25-100 μm region. SPICA can cover this wavelength region, whereas JWST can observe shorter than 28 μm., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027083, レポート番号: JAXA-SP-17-010E}, pages = {381--382}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Disentanglement of Small-Scale Structures from the Zodiacal Dust Cloud}, volume = {JAXA-SP-17-010E}, year = {2018} }
