Understanding Asteroid Regolith Properties Using Solar System Dust Bands

Abstract

Following the discovery of the first young, still forming, partial zodiacal dust band, we have shown that partial bands retain significant information about both the size-frequency distribution and cross-sectional area of dust released in the disruption of their parent asteroids. The new observational constraints to our modeling work that are provided by the partial dust band allow us to begin to reconstruct the properties of the regolith on the surface of the parent asteroid before its collisional disruption, including the depth of the regolith and the size-distribution of the particles present. Using the constraints provided by modeling the partial dust band at 17°, we discuss the surface regolith of the parent asteroid to the Emilkowalski cluster and investigate the relationship between regolith depth and the size distribution of particles. By examining the available data for other asteroids, we determine a scaling relationship between depth of regolith and asteroid size.
