Expanding the Frontiers in Condensed Phase Astrochemistry:
Electron Transfer Processes in Ices and Catalysis on Interstellar Grains

253rd National Meeting, San Francisco, CA, 2 - 6 April 2017

The deadline for submitting an abstract is Monday 31 October 2016.

Prof. Ralf I. Kaiser (University of Hawaii)
Dr. Murthy Gudipati (Jet Propulsion Laboratory)


During the last decade, significant new experimental techniques have been developed to investigate the interaction of ionizing radiation (UV, VUV, gamma rays, charged particles) and neutrals (atoms, radicals, molecules, grains) with surfaces of solids (ices, minerals, carbonaceous compounds) in the Solar System and in the Interstellar Medium (ISM). These processes provide new fundamental insights - sometimes on the molecular level - into the chemical processes that are critical to the chemical evolution of the ISM, star and planet forming regions, and on/in icy objects in the Solar System covering a wide range from the formation of the simplest molecule (molecular hydrogen) to complex bio-relevant species such as amino acids and sugars. Two currently operating space missions to the Kuiper Belt (New Horizons) and to comet 67P/Churyumov-Gerasimenko (Rosetta) highlight the importance of these processes.

This 3.5 days (seven half day sessions) symposium features invited (senior and junior scientists) as well as contributed talks covering the interaction of ionizing radiation (UV, VUV, gamma rays, charged particles) and neutrals (atoms, radicals, molecules, grains) with low temperature solids (ices, minerals, organics), the formation of solids (interstellar grains; nanoparticles) from simple precursors via silicon- and carbon-bearing clusters, and the analysis of these processes both computationally and experimentally. Two special half-day sessions highlight how these investigations can be exploited to understand the data from the currently operating New Horizons and Rosetta Mission.

We anticipate 25 invited (30 min + 10 min discussion) and 25 contributed talks (15 min + 5 min discussion). Photo courtesy of Murthy Gudipati.
