This project will use observational data to investigate the physical processes at play in the Sun's atmosphere in the hours and day leading up to eruptive events known as coronal mass ejections. Data from the EIS instrument on Hinode will be used to probe the plasma properties whilst the telescopes on SDO will provide data on the configuration and evolution of the coronal magnetic field. It is known that magnetic reconnection plays a key role in priming the corona ready for an eruption, but little is currently known about the role the plasma plays and, conversely, what can be learnt about the magnetic field evolution from the plasma properties.

该项目将使用观测数据来研究导致日冕物质抛射爆发的太阳大气层的物理过程。日野号上的EIS仪器的数据将用于探测等离子体特性，而SDO上的望远镜将提供有关日冕磁场结构和演变的数据。众所周知，磁重联在准备日冕爆发的过程中起着关键作用，但目前对等离子体的作用知之甚少，相反，从等离子体的性质中可以了解到磁场的演变。
