High Angular Resolution Observations of Saturn at 21.1 CM Wavelength,

Abstract

Saturn was observed with an interferometer at a wavelength of 21.1 cm in an effort to determine whether any of the emission at this wavelength originates from outside the area of the visible disk. The result, in terms of upper limits, is that no more than 6 per cent can come from the visible rings nor more than 5 per cent from a radiation belt, assuming brightness distribution models that the authors describe. The latter limit implies that the volume emissivity of a hypothetical Saturn radiation belt has an upper limit of only about 1 per cent of that for Jupiter in corresponding regions. The measured disk temperature is 232 plus or minus 18K. (Author)
