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.

该项目的一般目标是使用分析方法和数值方法促进对对流过程驱动的波的激发机制的物理理解。我们正在埃克塞特组在旋转和非旋转恒星中恒星对流的多维流体动力学模拟。博士项目的一个目标是改善现有的分析理论，利用当前的观察结果和恒星对流的多维流体动力模拟的结果来描述波动激发机制。分析旋转对激发机制的影响和对波的性质的影响是该项目的另一个重要目的。
