Abstract
The Sun is a standard reference object for Astrophysics and also a
fascinating subject of study in its own right. X-ray and extreme ultraviolet
movies of the Sun's atmosphere show an extraordinary diversity of plasma
phenomena, from barely visible bursts and jets to coronal mass ejections that
impact a large portion of the solar surface. The processes that produce these
phenomena, heat the corona and power the solar wind remain actively studied and
accurate atomic data are essential for interpreting observations and making
model predictions. For the Sun's interior intense effort is focused on
resolving the "solar problem," (a discrepancy between solar interior models and
helioseismology measurements) and atomic data are central to both element
abundance measurements and interior physics such as opacity and nuclear
reaction rates. In this article, topics within solar interior and solar
atmosphere physics are discussed and the role of atomic data described. Areas
of active research are highlighted and specific atomic data needs are
identified.
太阳是天体物理学的标准参照物,其本身也是一个引人入胜的研究课题。太阳大气层的 X 射线和极紫外视频显示了非凡多样的等离子体现象,从几乎看不见的爆发和喷射到影响大部分太阳表面的日冕物质抛射。对产生这些现象、加热日冕和为太阳风提供动力的过程仍在进行积极的研究,准确的原子数据对于解释观测结果和进行模型预测至关重要。对于太阳内部,人们正集中精力解决 "太阳问题"(太阳内部模型与日光地震学测量之间的差异),而原子数据对于元素丰度测量和内部物理学(如不透明度和核反应速率)都至关重要。本文讨论了太阳内部物理学和太阳大气物理学的主题,并介绍了原子数据的作用。文章强调了正在进行的研究领域,并指出了具体的原子数据需求。
