摘要

日冕亮点(CBPs)是太阳活动的一个基本类别。它们代表了一组低日冕小环,在极紫外和x射线光谱中具有增强的发射,连接了相反极性的磁通量浓度。CBPs是活动区外太阳大气的主要组成部分之一,均匀分布在活动区纬度和日冕洞等太阳大气中。它们的等离子体特性将它们归类为缩小的活跃区域。最重要的是,它们结构简单,寿命短,不到20年?这为研究包括日冕加热在内的太阳物理学中悬而未决的问题提供了一个独特的机会。本期《生活回顾》是对这类太阳现象的首次回顾,旨在概述当前关于CBP一般、等离子体和磁性的知识。简要介绍了几种与CBPs相关的瞬态动力学现象。综述了观测推导的能量学和旨在解释CBP形成和喷发行为的理论模型。

Coronal bright points

Coronal bright points (CBPs) are a fundamental class of solar activity. They represent a set of low-corona small-scale loops with enhanced emission in the extreme-ultraviolet and X-ray spectrum that connect magnetic flux concentrations of opposite polarities. CBPs are one of the main building blocks of the solar atmosphere outside active regions uniformly populating the solar atmosphere including active region latitudes and coronal holes. Their plasma properties classify them as downscaled active regions. Most importantly, their simple structure and short lifetimes of less than 20?h that allow to follow their full lifetime evolution present a unique opportunity to investigate outstanding questions in solar physics including coronal heating. The present Living Review is the first review of this essential class of solar phenomena and aims to give an overview of the current knowledge about the CBP general, plasma and magnetic properties. Several transient dynamic phenomena associated with CBPs are also briefly introduced. The observationally derived energetics and the theoretical modelling that aims at explaining the CBP formation and eruptive behaviour are reviewed.
