为了探讨太阳“超级耀斑”对空间天气的潜在影响,研究了太阳和日球观测站/LASCO日冕观测站观测到的能量大于10 MeV的高能质子峰值通量(Fp)、太阳附近日冕物质抛射速度(VCME)、在1996年至2014年记录的110次主要太阳质子事件期间,1-8毫米波段(FSXR)的耀斑软X射线峰值通量。线性回归拟合得到比例关系、和,α = 0.30 ± 0.04,β = 1.19 ± 0.08,γ = 4.35 ± 0.50。在简单的物理假设的基础上,另一方面,我们得到的标度关系表示日冕物质抛射质量(MCME),日冕物质抛射速度和高能质子通量的总耀斑能量(Eflare)的,和,分别。然后,我们结合联合收割机导出的标度关系与观测和估计的上限VCME和Fp与可能的太阳超耀斑。
In order to discuss the potential impact of solar “superflares” on space weather, we investigated statistical relations among energetic proton peak flux with energy higher than 10 MeV (Fp), CME speed near the Sun (VCME) obtained by Solar and Heliospheric Observatory/LASCO coronagraph, and flare soft X-ray peak flux in the 1–8 Å band (FSXR) during 110 major solar proton events recorded from 1996 to 2014. The linear regression fit results in the scaling relations , , and with α = 0.30 ± 0.04, β = 1.19 ± 0.08, and γ = 4.35 ± 0.50, respectively. On the basis of simple physical assumptions, on the other hand, we derive scaling relations expressing CME mass (MCME), CME speed, and energetic proton flux in terms of total flare energy (Eflare) as , , and , respectively. We then combine the derived scaling relations with observation and estimated the upper limit of VCME and Fp to be associated with possible solar superflares.
