Short summary
Space plasmas often deviate from the usual thermal pattern assumed in most models. Using the standard Kappa distribution, we derived how this non-thermal energy spread alters electrical flow, heat transfer, and particle motion. We found that stronger deviations lower collision rates and enhance transport coefficients, while normal behaviour returns in the thermal limit, which improves our insight into space environments.
