Stellar seismology: Models and numerical simulations of waves in rotating stars

该项目的总体目标是利用解析和数值方法推进对对流过程驱动波的激发机制的物理理解。我们正在埃克塞特小组进行旋转和非旋转恒星对流的多维流体动力学模拟。博士项目的一个目标是利用当前的观测结果和恒星对流的多维流体动力学模拟结果来改进现有的描述波激发机制的分析理论。分析旋转对激励机制和波的性质的影响是这个项目的另一个重要目标。

The general goal of the project is to advance on the physical understanding of the excitation mechanisms of waves driven by convective processes, using both analytical and numerical approaches. We are performing in the Exeter group multi-dimensional hydrodynamic simulations of stellar convection in rotating and non rotating stars. One goal of the PhD project is to improve existing analytical theories describing wave excitation mechanisms using current observations and the results of multi-dimensional hydrodynamic simulations of stellar convection. Analysing the impact of rotation on the excitation mechanisms and on the properties of waves is another important aim of this project.
