论文摘要
我们检查了太阳耀斑和CME驱动的电击中的能量中性原子（ENA）的产生，并随后传播到1 AU。对于两种情况，计算了1 Au处太阳能ENA的时间曲线和通量光谱：1）在CME驱动的电击下下游产生ENA，并且2）2）在太阳能耀斑中大规模的爆发后环上产生ENA。这两种情况的时间概况和通量光谱都大不相同。我们的计算表明，我们可以使用太阳能ENA作为新的探针来检查太阳能颗粒（SEP）的潜在加速过程，并区分两个加速位点：在大型SEP事件中，太阳能耀斑和CME驱动的电动冲击的下游中的大循环。
We examine the production of energetic neutral atoms (ENAs) in solar flares and CME-driven shocks and their subsequent propagation to 1 au. Time profiles and fluence spectra of solar ENAs at 1 au are computed for two scenarios: 1) ENAs are produced downstream at CME-driven shocks, and 2) ENAs are produced at large-scale post-flare loops in solar flares. Both the time profiles and fluence spectra for these two scenarios are vastly different. Our calculations indicate that we can use solar ENAs as a new probe to examine the underlying acceleration process of solar energetic particles (SEPs) and to differentiate the two accelertion sites: large loops in solar flares and downstream of CME-driven shocks, in large SEP events.
