| Research Abstract |
We propose a chain accretion scenario for the origin of the architecture of the giant planets in the solar system, in which planetary accretion proceeds sequentially from Jupiter to Neptune. To inspect this scenario we develop a special simulator "solar system formation simulator" that utilizes a special-purpose computer for many-body problems. Using this simulator we investigate globally the oligarchic growth of protoplanets that is an important base of the scenario. We find that even with the snow line(surface density jump due to ice condensation) the oligarchic growth model holds.
