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…
The full curvature effect expected in early X-ray afterglow emission of gamma-ray bursts
Y. -P. Qin
We explore the influence of the full curvature effect on the flux of early X-ray afterglow of gamma-ray bursts (GRBs) in cases when the spectrum of the intrinsic emission is a powe…
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…
A test of the power law relationship between gamma-ray burst pulse width ratio and energy expected in fireballs or uniform jets
Z. -Y. Peng, Y. -P. Qin, B. -B. Zhang +3
Recently, under the assumption that the Doppler effect of the relativistically expanding fireball surface is important, Qin et al. showed that in most cases the power law relations…
Physical implication of the Kocevski Ryde Liang pulse function of gamma ray bursts
Z. -B. Zhang, Y. -P. Qin
In this paper, we contrast an empirical pulse function of gamma-ray bursts with a theoretical model in order to provide a physical explanation to the parameters of the KRL function…
Spectral lags caused by the Doppler effect of fireballs
R. -J. Lu, Y. -P. Qin, Z. -B. Zhang +1
Recently, Shen et al. (2005) studied the contributions of curvature effect of fireballs to the spectral lag and showed that the observed lags could be accounted for by the effect.…
