Inner heliosphere studies of the solar wind

空间与大气物理小组正在领导为定于2019年发射的太阳轨道器使命开发磁力计。太阳轨道器将携带一套遥感和现场仪器，距离太阳0.28 Au。该使命旨在将联合收割机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日冕中起源的问题;以及太阳瞬变如何驱动日光层的变化？这个博士项目将利用现有的遥感和现场数据集，以解决与太阳轨道器科学相关的问题。一个可能的初步项目可以利用以前确定的由径向排列的航天器观测到的日冕物质抛射的例子，研究日冕物质抛射的现场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，侵蚀的CME磁结构发生通过重联。

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.
