Electrons in the Collisionally Young Solar Wind: Parker Solar Probe Observations

We report new observations by the Parker Solar Probe of unique electron velocity distribution functions (VDFs) in low-density solar wind streams at heliocentric distances of ∼10–20 R _⊙ . These VDFs have a significant core anisotropy and lack a clear energy spectral break point between the thermal c...
