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.
