| Outline of Final Research Achievements |
Formation of organic molecules on the surface of solid materials in protoplanetary disks are experimentally performed. Gas species are hydrogen and carbon oxide, the two most abundant species, and the solids are Fe-, Ni-, and FeNi- metals and amorphous silicate. Methane and linear chain compound are formed. The reaction takes place at lower temperatures on ice than that on amorphous silicates.
Micro-XANES equipment has been developed in a beam line of Spring-8 in order to observe organics formation reactions in situ and analyze the chemical bonds. The new equipment enables us to observe and analyze organic and inorganic materials by using energy edges, which was used for the experimental samples by other teams of the current research project. Theoretical study on the surface of silicates, metals, and amorphous silicate were conducted on the basis of the first principle calcuration. A new physico-chemical model on the solar system evolution has been developed.
