Keywords太陽系 / 原始惑星系円盤 / 地球外有機物 / リュウグウ / 再現実験
Outline of Research at the Start

地球外有機物の精密分析と再現実験により,太陽系形成時の初期化学状態を解明する.隕石,惑星間塵,「はやぶさ2」が持ち帰るC型小惑星リュウグウ試料中の有機物の総合分析をおこない,元素・同位体組成,分子構造などを決定する.これらの有機物は太陽系形成時につくられた後,原始太陽系円盤や小天体で変質し,現在の状態になっている.共存鉱物から,有機物が経験した変質過程を推定し,変質前の太陽系最初期有機物の化学状態を制約する.光化学反応有機物形成実験,および有機物やケイ酸塩の変質実験をおこない,太陽系最初期有機物ならびにその形成と変化を再現する条件を明らかにする.

Outline of Annual Research Achievements

太陽系も他の惑星系と同様,原始太陽の周囲に原始太陽系円盤がつくられることで誕生した.原始太陽系円盤も,電波天文観測で捉えられている惑星系形成領域の多様な化学環境のいずれかを初期状態とし,地球を含む惑星に至るまで進化したと考えられる.分子で観測される惑星系形成領域の化学的多様性に,太陽系の初期状態がどのように位置づけられ,太陽系がその形成時にどのような化学過程を経たのか,を明らかにすることが本課題の目的である.中間温度・中間密度環境で様々な化学反応が起こりうる惑星系形成領域での多様な化学を理解するためには,観測や分析の結果のみから推定するのではなく,原子・分子レベルでの素過程に立ち戻り,新たな学理を構築する必要がある.本領域で物理・化学分野との協働で進める素過程の解明に基づき,惑星系形成領域の化学的多様性を理解し,太陽系の初期化学状態をその中に位置づけることを目的とする.当該年度は小惑星探査機「はやぶさ2」が持ち帰った近地球C型小惑星リュウグウ試料の初期分析をおこない,無機化学(元素,同位体)・鉱物学・岩石学・有機化学(固体有機物,可溶性有機分子)の観点から,その詳細を明らかにし,既存の隕石との比較をおこなった.また,リュウグウに存在する鉱物のひとつである炭酸塩の真空分解実験をおこない,分解速度をもとにして,リュウグウが近地球側小惑星として経験した最も太陽に近い軌道条件の制約をおこなった.

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

小惑星リュウグウ試料の分析が順調に進んでいる.

Strategy for Future Research Activity

小惑星リュウグウ試料の分析結果に基づき,小惑星での変成・変質条件の実験も進めている.これらの結果を利用した有機物の再現・変成実験をおこなっていく.
