Astrochemistry and surface science

Surface science try to model ideal systems.   In particular in the region close to dying stars, temperatures and pressures are very similar to those that we can obtain in the laboratory. This is a picture of the Stardust machine, an UHV machine built to mimic the formation of cosmic dust and its interaction with the gas within the frame of the NANOCOSMOS ERC Synergy Grant Project

surface science has been used to present a model of PAH formation our of processing of SiC grains in the circumstelar medium.
