Abstract

In this review, our present day understanding of the Sun’s global photospheric and coronal magnetic fields is discussed from both observational and theoretical viewpoints. Firstly, the large-scale properties of photospheric magnetic fields are described, along with recent advances in photospheric magnetic flux transport models. Following this, the wide variety of theoretical models used to simulate global coronal magnetic fields are described. From this, the combined application of both magnetic flux transport simulations and coronal modeling techniques to describe the phenomena of coronal holes, the Sun’s open magnetic flux and the hemispheric pattern of solar filaments is discussed. Finally, recent advances in non-eruptive global MHD models are described. While the review focuses mainly on solar magnetic fields, recent advances in measuring and modeling stellar magnetic fields are described where appropriate. In the final section key areas of future research are identified.

太阳的全球光球和日冕磁场:观测和模型
在这篇综述中,我们从观测和理论两个角度讨论了我们目前对太阳全球光球和日冕磁场的认识。首先介绍了光球磁场的大尺度特性,以及光球磁通量输运模型的最新进展。在此之后,描述了用于模拟全球日冕磁场的各种理论模型。在此基础上,讨论了磁通量输运模拟和日冕模拟技术在日冕空穴、太阳开放磁通量和太阳细丝半球分布等现象中的联合应用。最后,介绍了非喷发型全球MHD模型的最新进展。虽然审查主要集中在太阳磁场,但在适当的地方描述了测量和模拟恒星磁场的最新进展。在最后一节,确定了未来研究的关键领域。
