Description
We performed an extensive observing programme on the zodiacal light with ISOPHOT. The mapping of several ~0.5degx0.5deg fields demonstrates the sub-percentage smoothness of the zodiacal light brightness on arcminute scale. The analysis of 27 ISOPHOT-S spectra in the 5-12μm range revealed blackbody-like spectral shapes with no obvious spectral features. The derived temperatures increase with ecliptic latitude and decrease with distance from the Sun in the range of 260-290 K. New interesting results are expected from multifilter photometry of the interplanetary dust cloud, and from observations of the asteroidal bands as well as of a cometary dust trail.
