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 enhance..., Two modeles has been used to calculate these datasets:
1, Multi-fluid MHD model if dust in the solar wind
2, Hall MHD model on interlaced magnetic flux ropes. Two cases are available: H=+1 and -1 for the flux rope at x>0.
They are not processed. They are raw model results.
