Variabilities of Gamma-Ray Bursts from the Dynamics of Fallback Material after Tidal Disruption by Yun-Peng Li, Da-Bin Lin, Guo-Yu Li, Zi-Min Zhou, En-Wei Liang

“…Turbulence induced by tidal force and the self-gravity of the debris may imprint variabilities in d M / d E during fallback. We model these fluctuations with a power density spectrum $\propto \,{f}_{{\rm{E}}}^{\beta }$ , where f _E  = 1/ E and β is the power-law index. …”
