Title: Connecting dynamical families in the Jovian System to Trojan Asteroids

Abstract: The capture of the irregular satellites of Jupiter lies as an important end point to dynamical models of solar system evolution. Understanding the compositions within the various dynamical families of irregular satellites via reflectance spectroscopy serves as a method to investigate their parent sources and determine if they share origins with Jupiters Trojan asteroids. Previously, photometric studies of irregular satellites have found similar colors within the same dynamical family. Additionally, NIR spectroscopy have found strong matches between Himalia and Elara, two large satellites (diameters > 70 km) in the Himalia dynamical family. This spectral evidence suggests that they may have formed from the disruption of a larger parent. However, comparisons made using only the largest bodies of a population may not reflect its full range of diversity. To date, only the largest irregular satellites have been studied in the VNIR. This observational bias limits the ability for spectral studies to make conclusive statements to their origins of the irregular satellites.
