| 单词 | f-corona |
| 释义 | F-coronaF-coronaThe outer part of the solar corona, responsible for the greater part of its intensity beyond a distance of about two solar radii. It consists of relatively slow-moving particles of interplanetary dust and exhibits an absorption spectrum because the particles scatter light from the photosphere. The F-corona extends for many million kilometers into the interplanetary medium and merges, in the plane of the ecliptic, with the particles that give rise to the zodiacal light. |
