γ射线暴的时变分析

On the Temporal Analysis of the Gamma-Ray Bursts

γ射线暴是天空中突然的硬X射线/γ射线爆发现象,有着非常复杂的光变曲线。由于光变现象和辐射过程直接相关,因此,研究γ射线暴的时变规律是非常重要的。对γ射线暴的一些时变现象以及通过时变研究得出的分类、脉冲形状、功率谱、时间演化、光度等性质进行了总结,并对一些结果进行了讨论。

The gamma-ray bursts (GRB) are the sudden flashes of the hard X/γ-rays in the sky with very complicated light curves. The temporal behavior of the bursts is directly related to their emission processes, therefore it is highly worth while to analyse the laws of the GRBs' temporal behavior. The morphology of GRBs' temporal behavior, and some work derived from the temporal analysis of GRBs, e.g. the classifications, pulse shapes, power spectra, spectral evolution and luminosities of the GRBs, are reviewed and some results are discussed.
