太阳黑子半影的模型和观测

Models and Observations of Sunspot Penumbrae

J. M. Borrero

摘要:

太阳黑子半影之谜在过去的10年里一直受到严格的审查。在此期间,一些模型被提出和反驳,而幸存的模型则必须进行修改、调整和进化,以解释不断增加的观测约束。在这篇文章中,我将回顾两个现有的模型,强调他们的贡献,这一领域,但也指出他们的一些不足之处,以解释最近的一些观测在非常高的空间分辨率。为了帮助解释这些新的观察结果,我对每一个都提出了一些修改。这些修改使这两个看似相反的模型更接近,形成了一个与最近的3D磁流体动力学模拟一致的总体图像。

英文摘要:

The mysteries of sunspot penumbrae have been under an intense scrutiny for the past 10 years. During this time, some models have been proposed and refuted, while the surviving ones had to be modified, adapted and evolved to explain the ever-increasing array of observational constraints. In this contribution I will review two of the present models, emphasizing their contributions to this field, but also pinpointing some of their inadequacies to explain a number of recent observations at very high spatial resolution. To help explaining these new observations I propose some modifications to each of them. These modifications bring those two seemingly opposite models closer together into a general picture that agrees well with recent 3D magneto-hydrodynamic simulations.
