Cold gas phase chemistry pertains to all astrophysical environments targeted in this COST Action. The pre-stellar phase is characterized by gas and dust in dark (only cosmic ray irradiation) cold (10-30 K) and low density (103-105 cm-3) conditions. The same type of conditions are found in dark cold parts of hot cores/corinos and the outer cold regions of protoplanetary disks (beyond ~100 AU). In cold gas, the usual laboratory experiments are not meaningful. Specially designed experiments and theories are set up and their results incorporated in the large gas-phase chemical networks, such as UMIST or KIDA.

This WG of the Action will produce specially take care of ion and radical reactions, theoretically and experimentally. Also, collision excitation rate for COM’s, necessary for quantitative analysis of abundances, are within WG1 scope.

Theory meeting November 23 to December 8 in Garching,
