Outline of Research at the Start

太陽系の原材料となったダストは，太陽より前世代の恒星周囲でつくられたダストや，星間空間で破壊され，再生産されたダストと考えられる．これら太陽系原材料となった「太陽型ダスト（恒星周ダストと星間再生産ダスト）」が，太陽系最初期にガスとの酸素同位体交換を経て，地球や隕石の材料である「地球型ダスト」へと変身する過程に注目する．(1) ダストとガスとの酸素同位体交換反応に必要な原始太陽系円盤の物理化学条件を実験より定量的に決定する．(2) 隠された太陽系原材料物質を始原隕石中に発見することにより (1) の過程の証明をめざす．

Outline of Final Research Achievements

The oxygen isotope exchange rate between amorphous silicate dust and disk gas was determined by low-pressure experiments along with the temperature dependence of the exchange rate and the reaction mechanism. The oxygen isotope exchange between amorphous silicate dust and disk gas was found to be controlled by diffusion in the amorphous silicate. A theoretical equation predicting the temperature at which chemical reactions effectively occur in dust moving in a protoplanetary disk with steady accretion was constructed, and the oxygen isotope exchange temperature of submicron-sized amorphous silicate dust was determined. Oxygen isotope exchange is completed at 650-800 K and 750-900 K for amorphous forsterite and amorphous enstatite dust, respectively, indicating that the evolution of oxygen isotope composition from solar-type dust to Earth-type dust occurred in the early Solar System.

Academic Significance and Societal Importance of the Research Achievements

地球や月，火星，小惑星の構成物質の酸素同位体組成は，太陽とは異なり，太陽と同じ酸素同位体組成をもつ太陽系初期ダストが，原始惑星系円盤ガスと酸素同位体交換を起こし，地球型の酸素同位体に変化したと考えられている，本研究では，実験で非晶質ケイ酸塩ダストと円盤ガスとの酸素同位体交換速度を求めた．また，原始惑星系円盤でダストの化学反応が効率的に起こる温度を決定する理論式を構築し，フォルステライト・エンスタタイト・かんらん石組成の非晶質ケイ酸塩ダストについて，それぞれ 650-800，750-900，500-600 K で酸素同位体交換が完了し，太陽型ダストが地球型ダストへと進化しうることがわかった．
