| Popis: | To investigate the structure of interface between forsterite glass and amorphous H2O ice, we performed molecular dynamics calculations. The result shows that a low-density layer for both forsterite and ice exists in the interface. Furthermore, the decomposition of water molecules was observed in the interface, although the decomposition rate decreases as the temperature decreases. The decomposition mechanisms of H2O are important to understand not only to the origin of water on terrestrial planets but also to the chemical evolution processes of various molecules in interstellar molecular clouds. |
