Electron Kappa Distributions in the Solar Wind: Cause of the Acceleration or Consequence of the Expansion?

The electron velocity distribution functions in the solar wind, far from the Sun, clearly exhibit a Kappa-like suprathermal tail. Is this characteristic also present in the corona or is it simply the consequence of the solar wind expansion? We elaborate around this question in this short chapter by relying, among others, on the recent electron measurements, as close as 29 solar radii (RSun) from the Sun, by the Parker Solar Probe.
