Outline of Final Research Achievements

The purpose of this research is to develop a new calculation method and to study the planetary formation process by using the largest number of particles and the latest accelerators. By this study, it became possible to calculate the planetary formation of N-body simulations more than 1 million particles for the first time. In the N-body calculation using the large number of particles (10 million particles), the result of earlier growth of the planet has been obtained than ever, and this process will be clarified in detail in the future.
