On Yaglom's Law for the Interplanetary Proton Density and Temperature Fluctuations in Solar Wind Turbulence

Giuseppe Consolini, Tommaso Alberti, Vincenzo Carbone
2020 Entropy  
Here, we investigate the passive scalar nature of the solar wind proton density and temperature by looking for scaling features in the mixed-scalar third-order structure functions using measurements on-board  ...  We find a linear scaling of the mixed third-order structure function as predicted by Yaglom's law for passive scalars in the case of slow solar wind, while the results for fast solar wind suggest that  ...  McComas (Southwest Research Institute, USA) and the NASA-CDAWeb service staff (USA) for the data (available on the web) used in this work.  ...

We show that due to the expansion of the solar wind two new terms appear in the Yaglom law.  ...  mixed moment, and therefore they cannot be neglected in the evaluation of the energy cascade rate in the solar wind.  ...  Assuming a model for spherical symmetric expansion of the solar wind (Verma et al. 1995) and using proton temperature data, Vasquez et al. (2007) found the following expression for the proton heating  ...

The Solar Wind as a Turbulence Laboratory

Roberto Bruno, Vincenzo Carbone
2013 Living Reviews in Solar Physics  
the problem, based on the dynamics of complex systems, brought new important insights which helped to better understand how turbulent fluctuations behave in the solar wind.  ...  In this review we will focus on a topic of fundamental importance for both astrophysics and plasma physics, namely the occurrence of large-amplitude low-frequency fluctuations of the fields that describe  ...  From top to bottom: wind speed, magnetic field azimuthal angle, proton number density, density fluctuations and normalized density fluctuations, proton temperature, magnetic field magnitude, total pressure  ...
