[MGI30-P01] Giant Impact Simulations: Effects of Algorithm, Resolution, and Equation of State
キーワード：地球、月、巨大衝突
The giant impact hypothesis is a collision between two planetary embryos, which is originally suggested as the origin of the Moon.
To date, a number of numerical simulations have been carried out by the smoothed particle hydrodynamics (SPH) method to check whether the scenario can form the Moon.
As a result, it is believed to be the most favourable scenario as the origin of the Moon.
However, the effect of the resolution on the results of the giant impact simulations has not been surveyed yet.
In this presentation, we will report the results of the numerical simulations of the giant impact by changing the algorithm, resolution, and equation of state.
We employed the updated SPH method, density-independent SPH and Japanese supercomputer FUGAKU.
