This project develops a new analytical and numerical modelling framework for studying the role of plasma flows in forming twists in magnetic flux tubes. Twisted magnetic flux tubes are common structural features in the solar atmosphere, the largest of which are prominences. The formation mechanism of these structures is still an open question, and this project will explore the role of plasma flows in inducing twisted magnetic structures. Furthermore, the degree of twisting can lead to instability and subsequent eruption. Understanding these prominence eruptions is key to understanding the birth of space weather events near the Sun.

本项目开发了一种新的分析和数值模拟框架，用于研究等离子体流在磁通管中形成扭曲的作用。扭曲的磁通管是太阳大气中常见的结构特征，其中最大的是日珥。这些结构的形成机制仍然是一个悬而未决的问题，本项目将探索等离子体流在诱导扭曲磁结构中的作用。此外，扭曲的程度可能导致不稳定和随后的喷发。了解这些日珥爆发是了解太阳附近空间天气事件诞生的关键。
