11 -- Chemical Constraints on the Formation and Evolution of Habitable Worlds

Description

We propose to organize a session at AbSciCon 2008 that will focus on understanding the origin and evolution of organic molecules and other volatiles in planet-forming disks, and the processes that lead to the formation of a habitable planetary system. Several fundamental problems in planet formation and habitability can only be addressed through a multi-disciplinary approach. Examples include: a) constraining the major element composition and the origin of volatiles in terrestrial planets; b) the evolution of organic compounds in primordial gas-rich disks, which are the initial conditions of habitable planetary systems; and c) predicting the diverse characteristics of terrestrial planets based on the protoplanetary environments in which they are formed.

AbSciCon provides a unique opportunity to bring together relevant experts from many fields to consider these questions from an astrobiological point of view. This session invites contributions from the astronomical, cosmochemical, astrochemical, and planetary communities and should engage in a lively discussion that probes the limits of our current knowledge.
