论文摘要
富含3HE的太阳能颗粒（SEP），表现出稀有元素（如3HE或超重核）的10,000倍丰度增强，已成为50多年来的难题。目前缺乏对3he 3he的SEP缺乏了解的原因之一是难以解决这些常见事件的来源区域。自从他们发现以来，有充分的证据表明3he富集的Sep产量与阳光下的耀斑有关。 3he丰富的SEP的异常丰度归因于必须在耀斑位点常规运行的独特加速机制。经常以类似射流的形式观察到与3HE富集相关的耀斑，表明磁性重新连接的加速度涉及通向行星际空间的野外线。由于太阳周围的航天器机队，提供了太阳成像观察的大大改进，现在以前所未有的细节探索了3he丰富的SEP来源。本文概述了当前对3HE富裕SEP的理解，主要关注其太阳能来源。
3He-rich solar energetic particles (SEPs), showing up to a 10,000-fold abundance enhancement of rare elements like 3He or ultra-heavy nuclei, have been a puzzle for more than 50 years. One reason for the current lack of understanding of 3He-rich SEPs is the difficulty resolving the source regions of these commonly occurring events. Since their discovery, there has been strong evidence that 3He-rich SEP production is associated with flares on the Sun. Anomalous abundances of 3He-rich SEPs have been attributed to a unique acceleration mechanism that must routinely operate at flare sites. Flares associated with 3He-rich SEPs have been often observed in jet-like forms indicating an acceleration in magnetic reconnection involving field lines open to interplanetary space. Owing to a fleet of spacecraft around the Sun, providing a greatly improved resolution of solar imaging observations, 3He-rich SEP sources are now explored in unprecedented detail. This paper outlines the current understanding of 3He-rich SEPs, mainly focusing on their solar sources.
