Two types of softening detected in X-ray afterglows of Swift bursts: internal and external shock origins?
Y. -P. Qin, A. C. Gupta, J. H. Fan +1
The softening process observed in the steep decay phase of early X-ray afterglows of Swift bursts has remained a puzzle since its discovery. The softening process can also be obser…

Hardness ratio evolutionary curves of gamma-ray bursts expected by the curvature effect
Y. -P. Qin, C. -Y. Su, J. H. Fan +1
We have investigated the gamma-ray bursts pulses assumed to arise from relativistically expending fireballs. We find, due to the curvature effect, the evolutionary curve of the raw…

Parameters of the prompt gamma-ray burst emission estimated with the opening angle of jets
B. -B. Zhang, Y. -P. Qin
We present in this paper an approach to estimate the initial Lorentz factor of gamma-ray bursts (GRBs) without referring to the delayed emission of the early afterglow. Under the a…
