太阳宏观电场测量进展
Advances in Measurement of Solar Macroscopic Electric Fields
摘要
Abstract
The macroscopic electric field plays a central role in solar flares and filament eruptions for magnetic energy conversion to plasma acceleration and heating, and energetic particle acceleration.Their distribution on the Sun is essential for quantitative studies of how energy flows from the Sun's photosphere, through the corona, into the heliosphere.However, so far more efforts have been made to detect the magnetic field on the Sun instead of the electric field.In recent years, with more and more space-exploring satellites being launched, a huge amount of high quantity data have been obtained, which have greatly deepened our knowledge about the physical processes of solar magnetic activities.Despite these achievements, we still have not clear understanding about the mechanisms of flares and filament eruptions, and the corona heating.To break through these difficulties, it is of importance for us to push forward the diagnosis of the macroscopic electric fields on the Sun.In this paper, we first review the main advances in the direct/indirect measurements of solar macroscopic electric fields, then suggest some detectable objects regarding the electric fields for the ongoing Chinese Giant Solar Telescope.关键词
