"The Origin and Evolution of Interplanetary Dust"
The origin of interplanetary dust was long thought to be cometary. This dramatically changed in the 1980s when dust production regions in the main asteroid belt were directly observed by the Infrared Astronomical Satellite. Since then, an increasing body of spacebased in situ and remote sensing observations, coupled with dynamical studies, have increased the complexity of both issues and answers - extending them to even the Kuiper Belt. By understanding the origin and evolution of our own interplanetary dust cloud, we are able to use our solar system as ground truth in understanding the similar production of dust around other stars, and compare what is going on in those other solar systems to what may have occurred in the past or will occur in the future of our own.
