ELECTRON HEAT CONDUCTION IN THE SOLAR WIND: TRANSITION FROM SPITZER-HÄRM TO THE COLLISIONLESS LIMIT

We use a statistically significant set of measurements to show that the field-aligned electron heat flux q sub(||) in the solar wind at 1 AU is consistent with the Spitzer-Harm collisional heat flux q sub(sh) for temperature gradient scales larger than a few mean free paths L sub(T) [> ~] 3.5[lam...
