…The flow speed of the solar wind is slow at about 300 km/s at the boundary of this sector, and reaches 700 km/s in between. Parker gave a basic theoretical explanation for the solar wind to explain the phenomenon of the tail of a comet being blown away just before an artificial satellite was launched, and this theory was verified by an artificial satellite, which had a dramatic history of discovery. The escape velocity from the solar surface is about 600 km/s, and any object thrown out at a speed slower than this should be held back by gravity and fall back onto the solar surface. … *Some of the terminology that mentions "Parker, EN" is listed below.

…太陽風の流速はこのセクターの境界では300km/s程度と遅く,その中間では700km/sに達する。太陽風についてはパーカーE.N.Parkerがすい星の尾が吹き流される現象の説明のために,人工衛星の上がる直前に基本的な理論的説明を与え,これが人工衛星によって検証されるという劇的な発見史をもつ。太陽面からの脱出速度は600km/s程度で,これより小さい速度で投げ出された物体は重力で引き止められて再び太陽面に落下してしまうはずである。… ※「Parker,E.N.」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 |
