Self-Organization through the Inner Heliosphere: Insights from Parker Solar Probe

The interplanetary medium variability has been extensively studied by means of different approaches showing the existence of a wide variety of dynamical features, such as self-similarity, self-organization, turbulence and intermittency, and so on. Recently, by means of Parker solar probe measurements, it has been found that solar wind magnetic field fluctuations in the inertial range show a clear transition near 0.4 AU, both in terms of spectral features and multifractal properties. This breakdown of the scaling features has been interpreted as the evidence of a dynamical phase transition. Here, by using the Klimontovich S-theorem, we investigate how the process of self-organization is under way through the inner heliosphere, going deeper into the characterization of this dynamical phase transition by measuring the evolution of entropic-based measures through the inner heliosphere.

The variability of the interplanetary medium has been extensively studied, revealing a wide variety of dynamical features. Recent measurements from the Parker Solar Probe have shown a clear transition in solar wind magnetic field fluctuations near 0.4 AU, indicating evidence of a dynamical phase transition. By using the Klimontovich S-theorem, researchers can investigate the process of self-organization in the inner heliosphere and measure the evolution of entropic-based measures to further characterize this dynamical phase transition.
