寻找太阳磁场的成因
Hunting down the cause of solar magnetism
摘要：
要了解太阳和恒星发电机结合本地和全球的数值模拟与长期观测是一项具有挑战性的任务：即使有最先进的计算方法和资源，恒星参数制度仍然无法实现。我们的目标是放松一些近似，以模拟更真实的系统，并尝试将结果与理论预测和最先进的观测结果联系起来。我们在这里提出了第一个测试场测量从我们的更高分辨率的运行与改进的热传导描述。它们表明与太阳和恒星发电机机制有关的最重要的感应效应的轮廓发生了显着变化。目前正在进行的更高分辨率的运行将使我们进入一个更加动荡的状态，在这种状态下，我们将能够首次以定量的方式研究小型和大型发电机的相互作用。
英文摘要：
To understand solar and stellar dynamos combining local and global numerical modelling with long-term observations is a challenging task: even with state of the art computational methods and resources, the stellar parameter regime remains unattainable. Our goal is to relax some approximations, in order to simulate more realistic systems, and try to connect the results with theoretical predictions and state-of-the-art observations. We present here the first test-field measurements from our higher-resolution runs with improved heat conduction description. They indicate significant changes in the profiles of the most crucial inductive effect related to solar and stellar dynamo mechanisms. Higher resolution runs, currently undertaken, will bring us into an even more turbulent regime, in which we will be able to study, for the first time, the interaction of small- and large-scale dynamos in a quantitative way.
