Is icy grains of dense molecular clouds at the origin of a fraction of the organic content of meteorites?
Résumé
Carbonaceous chondrites are sources of information witness on the origin of the solar system. Their organic content is conventionally classified as soluble (SOM) and insoluble organic matter (IOM), where the latter represents the majority of their organic content. Relationships between SOM and IOM are still unknown, and their possible link is still debated. Using laboratory experiments, processes possibly at the origin of SOM and IOM are investigated, by assuming that dense molecular ices is one of the sources of organic matter of the solar system. Each organic fraction is analyzed by different analytical technics providing a complete information on their composition and evolution.
