PHYSICS OF ZODIACAL DUST

This review of the physics of zodiacal dust seeks to present a consistent framework to model the dust as nonspherical and inhomogeneous chondritic aggregates ranging from compact to highly porous structures. The objective is to address all aspects needed to model the optical, thermal, and dynamic properties of the zodiacal cloud. A chronological model relating zodiacal dust to solar nebula dust and interstellar grains gives a theoretical basis for the chondritic aggregate model of interplanetary matter and provides a framework to relate specific models to their origin. -from Author
