Keywords	原始太陽系 / 惑星 / 巨大惑星 / 隕石 / 二次大気 / 地球型惑星 / 原始太陽系星雲 / 太陽系起源
Research Abstract	重点領域研究「原始太陽系と惑星の起源」に関し、i)太陽系星雲の起源と変遷、ii)臣大惑星の起源と進化、iii)隕石の起源と母天体、iv)地球型惑星の起源と構造、v)惑星の大気の起源と変遷、vi)太陽系の起源にかかわる惑星探査の基礎、の6班を構成し、昭和62年度より平成元年度までの3年間にわたり研究を推進した。本研究はこの重点領域研究の成果をとりまとめ、その資料に基づき欧文出版を行い、成果を広く世に残すことを目的としている。成果取りまとめ及び出版編集会議は4回開催され、全般にわたる研究成果の評価、検討を行った。その結果、本重点領域研究が太陽系形成の研究に果たした大きな貢献を欧文図書として刊行することが決定された。出版される欧文図書は、国際的に広いレベルで、太陽系星雲の誕生、その中での巨大惑星の誕生、地球型惑星の研生、そして隕石によるその足取りの解明、惑星の大気の生成と変遷を内容とし、広く一般にも理解されるものであると同時に、先導性を持ってわが国のこの方面における学術のレベルを上げ、次代の研究者の養成にも不可決な資料としての意義を持つものである。刊行図書の標題は、「Primitive Solar Nebula and Origin of Planets」とし第1章太陽系星雲第2章巨大惑星の起源第3章小天体と地球型惑星の起源第4章隕石の起源第5章惑星大気の変遷第6章太陽系の探査を内容として、執筆・編集が進められた。本年度内に全ての作業が終了し、本研究の目的が達成された。
