亚巴秒VAULT观测揭示的上色球层和下过渡区的结构和动力学
The Structure and Dynamics of the Upper Chromosphere and Lower Transition Region as Revealed by the Subarcsecond VAULT Observations
摘要：
甚高角分辨率超紫外望远镜是一个探空火箭有效载荷，用于通过观测太阳光谱中最强的线，即1216 ° C的Ly-a线，研究太阳色球层和日冕之间的关键界面。在两次飞行中，VAVEX成功地获得了该区域的首次亚弧秒（0.5”）图像，具有高灵敏度和节奏。对这些观察结果的详细分析大大有助于对过渡区域的性质提出新的看法。在这里，我们提出了一个广泛的概述Ly-a的大气层所揭示的VALENT观测，并汇集了过去的结果和新的分析，从第二VALENT飞行，创造一个综合我们目前的知识的高分辨率Ly-a太阳。我们希望这项工作将为即将到来的Ly-a望远镜和观测计划的设计提供很好的参考。
英文摘要：
The Very high Angular resolution ULtraviolet Telescope (VAULT) is a sounding rocket payload built to study the crucial interface between the solar chromosphere and the corona by observing the strongest line in the solar spectrum, the Ly-a line at 1216 Å. In two flights, VAULT succeeded in obtaining the first ever sub-arcsecond (0.5") images of this region with high sensitivity and cadence. Detailed analyses of those observations have contributed significantly to new ideas about the nature of the transition region. Here, we present a broad overview of the Ly-a atmosphere as revealed by the VAULT observations, and bring together past results and new analyses from the second VAULT flight to create a synthesis of our current knowledge of the high-resolution Ly-a Sun. We hope that this work will serve as a good reference for the design of upcoming Ly-a telescopes and observing plans.
