标题： 3D Numerical Experimentation on the Core Helium Flash of low-mass Red Giants

摘要： 我们使用Djehuty（一个完全三维（3D）的代码）对一颗低质量红巨星的核心氦闪进行了建模。 这些3D结构是从1D演化计算过程中获得的1$\Msun$恒星的收敛模型生成的。 无论我们采用哪种起始点，我们都发现经过一些瞬态放松后，3D模型稳定下来，其快速对流的氦燃烧壳层与1D模型预测的结果相差不大。 显示英文摘要

摘要： We model the core helium flash in a low-mass red giant using Djehuty, a fully three-dimensional (3D) code. The 3D structures were generated from converged models obtained during the 1D evolutionary calculation of a 1$\Msun$ star. Independently of which starting point we adopted, we found that after some transient relaxation the 3D model settled down with a briskly convecting He-burning shell that was not very different from what the 1D model predicted.
