Title: On the dust of primitive small bodies in the solar system

Abstract: Of around 4000 extrasolar planetary systems discovered as of October 2022, a sizable fraction of nearby solar-type stars are surrounded by dusty disks, analogous to the solar system’s small body reservoirs. The dust therein plays a central role in sculpting planetary systems as a building block of planetesimals and as a feedstock for synthesising complex organic molecules and ice that could be significant on habitability. As a result, the locations and physical properties of the dust in these dust structures provide essential probes of the processes of the formation and subsequent dynamical evolution of planetary systems, with our solar system being a reference thanks to its highest-ever accessibility. Comets and comet-like primitive asteroids represent the best opportunity to explore this fundamental thrust because they preserve the least-altered planetesimal left from the formative epoch. In this talk, I will introduce my recent works using various ground-based telescopes seeking to understand the structural evolution of our solar system and some relevant works of Comet Interceptor.
