日冕

白光日冕

日冕英语:Corona,拼音:rì miân)是太阳大气的最外层(其内部分别为光球层和色球层),厚度达到几百万公里以上。日冕温度有100万摄氏度,粒子数密度为10m。在高温下,氢、氦等原子已经被电离成带正电的质子、氦原子核和带负电的自由电子等。这些带电粒子运动速度极快,以致不断有带电的粒子挣脱太阳的引力束缚,射向太阳的外围。形成太阳风。日冕发出的光比色球层的还要弱。

日冕可分为内冕、中冕和外冕3层。内冕从色球顶部延伸到1.3倍太阳半径处;中冕从1.3倍太阳半径到2.3倍太阳半径,也有人把2.3倍太阳半径以内统称内冕。大于2.3倍太阳半径处称为外冕(以上距离均从日心算起)。广义的日冕可包括地球轨道以内的范围。

A corona (Latin, 'crown') is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. The word "corona" is a Latin word meaning "crown", from the Ancient Greek κορώνη (korōnè, “garland, wreath”).
