Development of the spectrum of gamma-ray burst pulses influenced by the intrinsic spectral evolution and the curvature effect
Y. -P. Qin
Spectral evolution of gamma-ray burst pulses assumed to arise from emission of fireballs is explored. It is found that, due to the curvature effect, the integrated flux and peak en…
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 softening phenomenon due to the curvature effect: in the case of extremely short intrinsic emission
Y. -P. Qin
The curvature effect is explored in the case of extremely short intrinsic emission. Assuming a function emission we get formulas that get rid of the impacts from the intrinsic…
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…
