Outline of Final Research Achievements |
By performing numerical-relativity simulations of the coalescence of binary neutron stars, we clarified the dynamics of the merger and the subsequent evolution of the system. We also clarified quantitatively the total amount of ejected materials as well as the thermodynamical and chemical properties of them. Using these data obtained, we performed nucleosynthesis calculations that proceed in the ejecta. As a main result, we concluded that the coalescence of binary neutron stars is the promising astrophysical origin of heavy element in the universe.
