摘要:

本文介绍了日冕-光子卫星上RT-2实验探测到的C2.7太阳耀斑的硬X射线观测分析结果。我们探测到周期为~12 s和~15 s的硬X射线脉动。我们发现了一个边际证据,表明随着时间的推移,周期在减少。我们使用RHESSI卫星的公开数据增强了这些结果。我们提出了一个频谱分析和测量光谱参数。

英文摘要:

We present the results of an analysis of hard X-ray observations of the C2.7 solar flare detected by the RT-2 Experiment onboard the Coronas - Photon satellite. We detect hard X-ray pulsations at periods of ~12 s and ~15 s. We find a marginal evidence for a decrease in period with time. We have augmented these results using the publicly available data from the RHESSI satellite. We present a spectral analysis and measure the spectral parameters.
