Magnetic field enhancements in the solar wind: Diverse processes manifesting a uniform observation type?

Within the solar wind throughout the inner heliosphere, observations
reveal the presence of magnetic field enhancements accompanied by thin
current sheets at varying distances from the sun and across different
longitudes and latitudes. Two primary explanations have been proposed to
elucidate these phenomena: Solar wind-dust interaction and interlacing
flux ropes. In this study, we employ multi-fluid Magnetohydrodynamics
(MHD) and Hall MHD models to simulate these hypotheses, respectively. Our
findings indicate a concurrence between both models and the observed
phenomena, suggesting that both processes may result in the same kind of
enhancement. Furthermore, both models make predictions pointing to
additional types of observational data, occurring at distinct spatial or
temporal stages of the interaction. This convergence of model predictions
with empirical data underscores the need for further observational and
modeling studies to comprehensively test these models. This research
enhances our knowledge of the inner heliosphere's dynamics and the
influence of the solar wind on the Earth's magnetosphere, thereby
shedding light on critical aspects of space weather and its potential
impact on our planet.
