Cross-correlation between the multifractal spectra of the solar wind magnetic field from Parker Solar Probe and Solar Orbiter

Abstract

Abstract The solar wind, a plasma emanating from the Sun and extending throughout the universe, continues to be a subject of intense study. This study focused on examining the multifractal spectra of the solar wind’s magnetic field in regions proximal and distal to the Sun, leveraging data collected by the Parker Solar Probe and Solar Orbiter satellites, respectively. Utilizing the box-counting method within multifractal analysis has provided insights into the distinctive characteristics of each satellite, including singularity exponents and multifractal spectra. However, the cross-correlation observed between the spectra obtained by both satellites has prompted further inquiry into its physical implications. This suggests the need for a more comprehensive investigation to elucidate the underlying dynamics driving these correlations and their significance in our understanding of solar wind behavior. Continued research in this area holds promise for advancing our comprehension of solar phenomena and their broader implications.
