论文摘要
我们介绍了有关非相互作用的冠状质量弹出（CME）和太阳能颗粒（SEP）的相关性的结果。在太阳周期24的上升阶段，即2009-2013，对25个SEP事件以及相关的CME和耀斑进行了统计分析，该阶段标志着太阳陆地关系观测站的正交配置（立体声）。 CME的完整运动学在立体声的这种配置附近进行了很好的研究。此外，我们对立体声和太阳能观测站（SOHO）结果进行了比较研究。众所周知，CME速度和SEP强度密切相关。我们通过采用瞬时速度（SEP峰值通量时的最大速度和CME速度和MACH数）来进一步检查这种相关性，以检查它们是否比平均速度更好地指示了SEP通量的指标。我们的初步结果表明，通过这种方法，相关性更好。此外，相关性表明，能量通道中质子的通量> 10 MeV是由快速CME产生的冲击波加速的，而> 50 MEV和> 100 MeV能量带的颗粒大多是由相同的冲击波加速的，但部分由相关的耀斑加速。相反，太阳耀斑和SEP峰通量的X射线通量显示出较差的相关性。
We present our results on the correlation of non-interacting coronal mass ejections (CMEs) and solar energetic particles (SEPs). A statistical analysis was conducted on 25 SEP events and the associated CME and flare during the ascending phase of solar cycle 24, i.e., 2009-2013, which marks the quadrature configuration of Solar TErrestrial RElations Observatory (STEREO). The complete kinematics of CMEs is well studied near this configuration of STEREO. In addition, we have made comparison studies of STEREO and SOlar and Heliospheric Observatory (SOHO) results. It is well known that the CME speeds and SEP intensities are closely correlated. We further examine this correlation by employing instantaneous speeds (maximum speed and the CME speed and Mach number at SEP peak flux) to check whether they are a better indicator of SEP fluxes than the average speed. Our preliminary results show a better correlation by this approach. In addition, the correlations show that the fluxes of protons in energy channel >10 MeV are accelerated by shock waves generated by fast CMEs, whereas the particles of >50 MeV and >100 MeV energy bands are mostly accelerated by the same shock waves but partly by the associated flares. In contrast, the X-ray flux of solar flares and SEP peak flux show a poor correlation.
