Abstract

A model describing the initial phase of the heating of a flare in the solar corona is proposed. The energy equation for a flare plasma in a magnetic tube is reduced to the two-dimensional equation of thermal conductivity with a nonlinear volume source that ensures the heating of the plasma in the blowup mode and nonlinear anisotropic thermal conductivity. Explosive plasma heating is shown to be accompanied by the formation of high-temperature filamentary structures elongated along the magnetic tube.

太阳耀斑早期丝状结构的形成

摘要

提出了描述太阳日冕中火炬加热的初始阶段的模型。利用非线性体积源将电磁管中火炬等离子体的能量方程式简化为热导率的二维方程式，以确保在爆炸模式下加热等离子体和非线性各向异性热导率。爆炸性等离子体加热显示伴随着沿磁管拉长的高温丝状结构的形成。
