This research programme revolves around the idea of analysing, modelling, interpreting and understanding the dynamical processes occurring in solar and solar-terrestrial plasmas. It focuses on several key fundamental processes that are crucial in understanding the Sun-Earth environment. It uses direct measurements made within our solar system and numerical models to understand and validate this data. Its core focus is on advancing fundamental science. However, by doing so it will directly lead to a better understand of the effects of the sun on the terrestrial and other planetary environments, which has increasing importance for modern society.The research programme has two overall closely linked high level aims. The first is to better understand how the solar wind (the high velocity stream of magnetised matter emitted by the Sun) interacts with planets. The second is to understand the atmosphere of the Sun and its generation of the solar wind. The research is split into four projects. The first two projects address the first aim. Specifically they are focused on understanding the shock waves produced in front of the planets due to their interaction with the solar wind. These shock waves are the primary means by which the high speed solar wind is slowed down and heated just before in interacts with the immediate planetary environment. The second set of two projects address the second aim. Specifically they are focused on understanding how the extreme temperature changes throughout the Sun's atmosphere arise and how relatively small scale processes can cause these.The primary results from the research programme will be in advancing fundamental science. However, its impact goes beyond this. Only by understanding our own solar system are we able to better understand more distant systems, where we cannot send spacecraft to sample and make direct in-situ measurement. The impact of this the research programme includes helping answer questions such as whether exoplanets can harbour life and how supernovae accelerate matter to some of the highest energies know. As well as advancing the fundamental science, the results will help inform the analysis of data from, and design of future space missions to explore the immediate and wider environment in which we live. Its results are fundamental to achieving a better understanding of the wider space-environment that we live in and its effect of our immediate and future "living" environment. Society is becoming increasingly reliant on technology, which is often inherently linked to energy and communication networks. This better understanding of humanities natural environment will ultimately help plan for a safe and sustainable future.

该研究计划围绕分析，建模，解释和理解太阳和太阳交等离子体中发生的动态过程的思想。它着重于几个关键的基本过程，这些过程对于理解阳光 - 地球环境至关重要。它使用在我们的太阳系和数值模型中进行的直接测量来了解和验证这些数据。它的核心重点是推进基本科学。但是，通过这样做，它将直接可以更好地了解太阳对陆地和其他行星环境的影响，这对现代社会的重要性越来越大。研究计划具有两个整体密切相关的高水平目标。首先是更好地了解太阳风（太阳发出的磁化物的高速流）如何与行星相互作用。第二个是了解太阳的气氛及其产生太阳风。该研究分为四个项目。前两个项目针对第一个目标。具体而言，由于它们与太阳风的相互作用，他们专注于理解行星前面产生的冲击波。这些冲击波是高速太阳风在与直接行星环境相互作用时加热和加热的主要手段。第二组项目解决了第二个目标。具体而言，他们专注于理解整个太阳大气中的极端温度如何变化以及规模相对较小的过程如何引起这些变化。研究计划的主要结果将是推进基本科学。但是，它的影响超出了这一点。只有了解我们自己的太阳系，我们才能够更好地理解更遥远的系统，在这种系统中，我们无法将航天器发送给样品并进行直接的原位测量。该研究计划的影响包括帮助回答诸如系外行星是否可以掩盖生命以及超新星如何加速物质到一些最高能量的问题。除了推进基础科学外，结果还将有助于为未来空间任务的数据分析和设计分析，以探索我们生活的直接和更广阔的环境。它的结果对于更好地了解我们居住的更广泛的太空环境及其对即时和未来的“生活”环境的影响至关重要。社会越来越依赖技术，这通常与能源和通信网络固有地联系在一起。对人文自然环境的更好理解最终将有助于计划安全和可持续的未来。
