研究亮暴和暗暴的X射线余辉,发现它们的X射线和γ流量的分布基本上相同。即:从统计学的角度上讲,亮暴和暗暴没有本质不同,它们的中心机制应该是相同的,暗暴的形成应该是由环境原因引起的。
A systematic study on the X-ray afterglows of the optically dark and bright gamma-ray bursts is presented. Our results show that the distribution of the X-ray, the 7-ray of the dark GRBs and bright GRBs are similar, any observed differences should be caused by simply statistical fluctuation. These results indicated that the suppression of optical emission in the dark GRBs should result in the circumambiency, not in their central engine.
