1995年以来、3000以上の太陽系外の惑星系が発見され、現在では惑星の質量・軌道分布のみならず、惑星大気の組成や質量についての統計的データが得られるようになってきた。太陽型の主系列星(FBK型星)の惑星系のみならず、赤色矮星(M型星)や質量が大きいA,B型星の惑星の観測も精力的に進み、近年では白色矮星の惑星のデータも得られるようになってきた。系外惑星系は多様な姿をとることがわかり、その多様系の起源が議論されるとともに、太陽系の形成過程が再検討されている。また、太陽系内の惑星には多様な姿の衛星系が存在し、衛星系の多様性の起源もあわせて議論されるようになってきた。他方、惑星表面に海が存在する可能性がある「ハビタブル・ゾーン」に地球サイズの惑星が多く存在することがわかり、太陽系内の氷衛星には内部海を持つものがいくつもあることがわかってきたことで、地球外生命の議論も活発になってきている。本講義では、惑星系と衛星系の形成と進化の理論モデルの概要について、最先端のトピックスも含めて述べる。

Since 1995, more than 3,000 extrasolar planetary systems have been discovered, and now it is possible to obtain statistical data on the composition and mass of the planetary atmosphere as well as the mass and orbital distribution of the planets. Not only the planetary system of the solar-type main sequence stars (FBK-type stars), but also the planets of red dwarfs (M-type stars) and larger-mass A and B-type stars have been observed. In recent years, data on planets around white dwarf planets has also come to be obtained. It has been found that exoplanet systems show diversity, the origin of the diverse systems is being discussed, and the formation process of the solar system is being reexamined. In addition, planets in the solar system have diverse satellite systems, and the origin of the diversity has also been discussed. On the other hand, it has been found that there are many earth-sized planets in the "habitable zone" where the oceans may exist on the surface of the planets, and that many ice satellites in the solar system have subsurface oceans. As a result, discussions on extraterrestrial life have become more active. In this lecture, I will give an overview of theoretical models of the formation and evolution of planets and satellite systems, including cutting-edge topics.
