Title: Keck HIRESb Observations of Comet 81P/Wild2: Unraveling the Chemistry of Comets

Abstract: We propose to use Keck HIRESb observations of comet 81P/Wild 2 in order to add constraints on the chemical formation and evolution of material which originated in the Kuiper belt. These observations will be combined with NIRSPEC observations (proposed elsewhere) to ascertain the relationship between the daughter species we observe in the optical and the parent species which are seen in the IR. By determining the reaction pathways, we get a more complete picture of the chemistry of comets, objects which are part of the building blocks of the outer Solar System. Wild 2 is optimally located for these observations. In addition, Wild 2 is an interesting comet because we have samples of its non-volatile composition in the laboratory as a result of the Stardust mission.
