…Another difficulty is that the rotation of the nebula itself, which has continued to shrink since the initial nebula, i.e. the Sun, must be much faster than it is today to match its mass. The importance of this angular momentum was pointed out by J. Babinet in 1961, and the peculiarities of the angular momentum distribution in the solar system were emphasized by M. Fouché in 1884 and FR Moulton in 1900, and became well-known, which led to the appearance of the following encounter theory. The planetesimal theory, which is one of the encounter theories, was proposed by TC Chamberlin and Moulton in 1900, and the tidal theory was proposed by JH Jeans and H. Jeffreys in 1917, but the two are very similar. … *Some of the terminology that mentions "Moulton, FR" is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…もう一つの困難は,最初の星雲から収縮に収縮を続けた星雲本体,つまり太陽の自転は,その質量に似合う程度に現在よりずっと高速でなければならないという点である。この角運動量の重要性は61年にバビネJ.Babinetが指摘し,太陽系における角運動量分布の特殊性は,84年フーシェM.Fouchéにより,1900年モールトンF.R.Moultonによって強調されて以来有名になり,以下の遭遇説が世に出るきっかけとなった。 遭遇説の中の微惑星説はチェンバレンT.C.Chamberlinとモールトンが1900年に提唱し,潮汐説はJ.H.ジーンズとジェフリーズH.Jeffreysが17年に提唱したものであるが,両者はよく似ている。… ※「Moulton,F.R.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
