摘要：
For gamma-ray bursts (GRBs), there may exist ring-shaped jet when the jet axis does not coincide with the spin axis of its source. Using some refined jet dynamics, we study multi-wavelength afterglow light curves for such ring-shaped jets. There is an obvious break in the afterglow light curve due to the beaming effect. We also investigate the effects of many key parameters on the light curves and then use our model to fit light curves of some GRBs.
