太阳暗条形成机制的观测研究

Solar filaments/prominences are one of the most common features in the solar atmosphere, consisting of cool dense plasma suspending in the hot sparse corona, and they occupy an important position in Solar Physics. Filaments are usually ejected with magnificent eruptions from the solar atmosphere, and have impacts on the space weather. The formation mechanism of filaments is always one of hot topics in Solar Physics, and it is significant to understand the mechanisms of the solar radiative transfer and the coronal heating. Combining with observations from the space-born and ground-based, we will mainly utilize the data from the New Vacuum Solar Telescope (NVST) of Yunnan Observatory, to study simultaneously filaments in multiple wavelengths and in different heights, from the photosphere, the chromosphere, the transition region, to the corona. We will analyze the magnetic structures of the filaments, and compare different models for the filament channel formation and mass source, and hope to obtain innovatory results on the formation mechanism of filaments.

暗条／日珥是一种最常见的太阳大气结构，由悬浮在高温稀薄日冕中的冷密物质组成，在太阳物理中占有重要地位。暗条经常伴随太阳大气中剧烈爆发一起释放，对空间天气有重要的影响。暗条的形成机制一直以来都是太阳物理的研究热点，对于理解太阳辐射转移机制和日冕加热都有重要的意义。本项目将联合使用云南天文台一米新真空太阳望远镜（NVST）高质量观测资料，结合其他天基和地基多波段数据，从光球、色球、过渡区到日冕，对暗条进行多波段、多层次的同步观测，研究暗条的磁场特征，对比不同的暗条通道形成机制和物质来源模型，以期在暗条的形成机制方面取得创新性成果。
