The Space & Atmospheric Physics group are leading the development of a magnetometer for the Solar Orbiter mission, due for launch in 2019. Solar Orbiter will carry a suite of remote sensing and in-situ instrumentation to distances as close as 0.28 AU from the Sun. The mission aims to combine these complementary observational techniques to answer questions such as how and where solar wind plasma and magnetic fields originate in the corona; and how solar transients drive heliospheric variability? This PhD project will exploit existing remote sensing and in-situ data sets to address questions relevant to Solar Orbiter science. A possible initial project could study the relationship between the in-situ observed properties of coronal mass ejections with their region of origin in the corona and how these subsequently evolve with distance from the Sun, taking advantages of previously identified examples of CMEs observed by radially aligned spacecraft. A particular question of interest is whether evidence can be found of erosion of the CME magnetic structure taking place through reconnection.

空间和大气物理小组正在领导太阳轨道飞行器任务的磁强计开发工作，该任务将于2019年发射。太阳轨道器将携带一套遥感和现场仪器，距离太阳最近0.28 AU。该飞行任务旨在结合这些互补的观测技术来回答一些问题，如太阳风、等离子体和磁场如何以及在哪里起源于日冕；以及太阳瞬变如何驱动日球层的可变性？这个博士项目将利用现有的遥感和现场数据集来解决与太阳轨道飞行器科学相关的问题。一个可能的初步项目可以研究日冕物质抛射的现场观测性质与它们在日冕中的起源区域之间的关系，以及这些性质随后如何随着距离太阳的距离而演变，利用以前由径向排列的航天器观测到的日冕物质抛射的例子。一个特别令人感兴趣的问题是，是否可以找到通过重新连接而发生的CME磁结构受到侵蚀的证据。
