英文摘要	The structure of the electron diffusion region (EDR), fundamental to a comprehensive theory of magnetic reconnection, is highly sensitive to asymmetry in the plasma parameters across the reconnection current layer. Using known scaling laws for the inflow region electron pressure anisotropy, a model is developed to predict the formation of extended electron jets within the EDR. Confirmed by kinetic simulation, the analysis shows how embedded electron jets are driven for scenarios fulfilling a generalized symmetry conditions based on the marginal firehose condition. ©2020.
