Inner heliosphere studies of the solar wind

空间与大气物理小组正在领导为太阳轨道飞行器任务开发磁力计，计划于2019年发射。太阳轨道器将携带一套遥感和原位仪器，距离太阳近至0.28 AU。该任务旨在将这些互补的观测技术结合起来，以回答诸如太阳风等离子体和磁场如何以及在何处起源于日冕等问题；太阳瞬变是如何驱动日球层变化的？这个博士项目将利用现有的遥感和原位数据集来解决与太阳轨道飞行器科学相关的问题。一个可能的初始项目可以利用先前确定的由径向对准的航天器观测到的日冕物质抛射的实例，研究日冕物质抛射的原位观测特性与其在日冕中的起源区域之间的关系，以及这些特性随后如何随着与太阳的距离而演变。一个特别令人感兴趣的问题是，是否可以找到证据证明CME的磁性结构是通过重联而受到侵蚀的。

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.
