项目摘要

We propose to undertake the following research projects.i) We will use supercomputer simulations to examine the evolution of the solar wind - thestream of charged particles that is constantly flowing from the Sun into our solar system.In particular, we will examine why this wind develops turbulence as it flows through interplanetaryspace, and how this turbulence heats the solar wind.ii) We will use supercomputer simulations to examine the low density but very high temperaturegas that lies above the Sun's surface - the solar corona. In particular, we want to understand howmagnetic field lines change their topology and release energy into the surrounding plasma by the process known as reconnection.iii) We will analyse images from the Cassini spacecraft that is currently orbiting Saturn, to examine how Saturn's moons interact with and disturb Saturn's system of rings. We are particularly interested in the F ring which lies near the outer edge of the ring system, and is regularly disturbed by two satellites, Prometheus and Pandora. We are also interestedin the A-ring, which appears to form long-lived clumps or moon-lets that are able to migratethrough the system. Finally, using accurate images of the Saturnian satellites, we will track theirmotion and measure the rate at which tidal energy is dissipated within Saturn.iv) We will attempt to understand more about the formation of the planet Mars. It is believedthat the four inner planets of our solar system formed from collisions between smaller bodiesthat built the planets, and we will use computer simulations to examine this process. We willexamine whether a collision can explain why Mars has a crust that is thicker in the southern hemisphere than in the north, and we will examine the formation of the satellites of Mars.

我们建议进行以下研究项目。位于太阳表面上方的温度气 - 太阳电晕。特别是，我们想了解磁场线如何通过称为Reconnection的过程更改其拓扑并将能量释放到周围的等离子体中。IIII），我们将分析目前正在绕土星的Cassini航天器中的图像，以检查土星的卫星如何与土星的卫星与环形的环境相互作用并令人不安。我们对位于环系统外边缘附近的F环特别感兴趣，并经常被两个卫星，Prometheus和Pandora打扰。我们也对A形环公司感兴趣，它似乎形成了能够迁移系统的长寿命团或月球。最后，使用土星卫星的准确图像，我们将跟踪它们的动态并衡量在土星中消散潮汐能的速度。据信，这是我们太阳系的四个内部行星是由较小的Bodiesthat之间的碰撞形成的，我们将使用计算机模拟来检查此过程。我们将遇到碰撞是否可以解释为什么火星在南半球比在北部更厚的地壳，我们将检查火星卫星的形成。
