日出任务亮点

Sunrise Mission Highlights

Tino L. Riethmüller, Sami K. Solanki

摘要:

太阳活动受磁场控制,磁场也会导致太阳辐照度的变化,进而影响地球上的气候。磁场以不同大小结构的形式表现出来,从太阳黑子(10-50微米)开始,一直到空间范围通常为100公里或更小的已知最小磁特征,对太阳磁场精细尺度结构的研究由于现有观测的空间分辨率有限而受到阻碍。由于新的太空和地面望远镜,这种情况最近发生了变化。日出天文台已经向前迈出了重要的一步,它围绕着最大的太阳望远镜建造,离开地面,并包含两个科学仪器。“日出”号于2009年6月(太阳活动最低期)和2013年6月(太阳活动最高期)在平流层气球上进行了两次成功的长期科学飞行,取得了一些科学成果,极大地推进了我们对太阳磁性的了解,数据分析仍在进行中。在简要介绍日出飞行任务之后,将概述这些结果的一部分。

英文摘要:

Solar activity is controlled by the magnetic field, which also causes the variability of the solar irradiance that in turn is thought to influence the climate on Earth. The magnetic field manifests itself in the form of structures of different sizes, starting with sunspots (10-50 Mm) down to the smallest known magnetic features that often have spatial extents of 100 km or less. The study of the fine scale structure of the Sun's magnetic field has been hampered by the limited spatial resolution of the available observations. This has recently changed thanks to new space and ground-based telescopes. A significant step forward has been taken by the Sunrise observatory, built around the largest solar telescope to leave the ground, and containing two science instruments. Sunrise had two successful long-duration science flights on a stratospheric balloon in June 2009 (solar activity minimum) and in June 2013 (at a high activity level) and a number of scientific results have been obtained that have greatly advanced our understanding of solar magnetism, with data analysis still ongoing. After a brief introduction to the Sunrise mission, an overview of a selection of these results will be given.
