Paper Abstract

The Aerospace model of the infrared radiation of the zodiacal light has been generalized to include the effects of scattered sunlight. The model has been compared with existing data on scattered visible light in order to test whether or not the infrared data are compatible with the visible data, i.e., can both the infrared and visible data be explained simultaneously by a single self-consistent model of the interplanetary dust? Both the IR emission and the visible scattering calculations are based on a Mie calculation, with the optical constants of the interplanetary dust being input parameters. The size and space distribution of the dust particles are explicitly parameterized; the model numerically integrates the results of the Mie calculations over the size distribution and along any chosen line of sight. The results show that the IR and visible data are in fact compatible. Both sets of data can be matched by the model by adjusting the continuous opacity within reasonable bounds. This is equivalent to adjusting the albedo of the particles. Furthermore, the size distribution function is very tightly constrained by comparing the predicted visible polarization of the model with existing data. This constraint leads to the conclusion that the IR emission cannot exhibit emission features.
