摘要:

利用小波分析方法研究了长、短Fermi/GBM伽马射线暴(GRB)光变曲线的时间变化。结果表明,在源帧中,变化的时间尺度为长爆发不同的短爆发,在几个毫秒的顺序的变化并不罕见,和一个有趣的关系之间存在的最小变化时间和爆发持续时间。

英文摘要:

We have investigated the time variations in the light curves from a sample of long and short Fermi/GBM Gamma ray bursts (GRBs) using an impartial wavelet analysis. The results indicate that in the source frame, the variability time scales for long bursts differ from that for short bursts, that variabilities on the order of a few milliseconds are not uncommon, and that an intriguing relationship exists between the minimum variability time and the burst duration.
