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.

该项目的总体目标是利用分析和数值方法，促进对对流过程驱动的波的激发机制的物理理解。我们在埃克塞特小组对旋转和非旋转恒星中的恒星对流进行了多维流体动力学模拟。PHD项目的一个目标是利用目前的观测和恒星对流的多维流体动力学模拟的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浪特性的影响是本项目的另一个重要目标。
