Outline of Final Research Achievements |
Zodiacal emission is thermal emission from interplanetary dust in our solar system. We analyzed zodiacal emission observed by the AKARI mid- and far-infrared all-sky survey, which covers 97% of the entire sky during the period 2006 April to 2007 August in six photometric bands, with central wavelengths of 9, 18 (mid-infrared), 65, 90, 140, and 160 μm (far-infrared). For the far-infrared survey data, we investigate the distribution of the small-scale dust-band structures in the AKARI all-sky maps and construct template maps of the asteroidal dust bands and the circumsolar ring components. Mid-infrared data suggests that the size of the smooth cloud, a dominant component in the zodiacal dust cloud model, is about 10% more compact than previously thought, and we detect a significant isotropically distributed dust cloud component.
