Title: What are Jupiter's irregular satellites? Testing Giant Planet Migration with JWST
Abstract: Jupiter's irregular satellites are small bodies thought to be captured from the hypothesized era of planet migration. Models of the formation and migration of giant planets predict that these small satellites were likely captured from the primordial Kuiper Belt. Placing constraints on their material composition(s) is critical to test whether irregular satellites share lineages with other captured populations (i.e., Jovian Trojan asteroids) and present-day Kuiper Belt objects. I will discuss the JWST Cycle 2 program I am leading to address these questions, with particular attention to how the unique collisional environment of irregular satellites may provide fundamental insights into the evolution of dark, carbonaceous surfaces.
