Evidence for a solar wind origin of the power law burst lifetime distribution of the AE indices

摘要: In this paper we examine the claim that power law distribution of burst lifetimes in AE index is evidence magnetosphere a Self-Organized Critical (SOC) system. To do compare lifetime distributions AU and |AL| indices with those υBs e solar wind input functions. We show for first time both are form an exponential cut-off, consistent being SOC Furthermore, not significantly different to indices, indicating scale-free property could arise from may be intrinsic magnetospheric discuss implications result theories magnetosphere.
