MULTI-SPECTRAL OBSERVATIONS OF A FLARE ON OCTOBER 27, 1992
-
摘要: 利用1992年10月27日耀斑极为完整的高质量观测资料,通过对可见光、软X射线和硬X射线图像和光谱的综合分析,诊断耀斑过程中的热与非热性质.结果表明,在这个事件中,热与非热过程并存且在时空演化上呈现不同的特征.Abstract: In this paper, a IN/M1.1 flare is studied in Ho, soft X-ray and hard X-rayemissions. Both thermal and nonthermal emissions are found in this flare whichdemonstrate various tempo-spatial features. Through investigating the observationsfrom all available wavelengths, the thermal or nonthermal properties of the flare canbe determined, with respect to which, distinctively different types of Her line profilesin different flare regions can be explained.
