Construction of solar-wind-like magnetic fields.
This Letter presents a method for constructing solar-wind-like magnetic fields that are nearly constant in magnitude, divergence-free, and match any specified fluctuation power spectrum. The approach selects relative phases between two polarizations per wave vector to minimize variance in field magnitude while keeping fields random. In a one-dimensional application, the constructed fields reportedly match observed solar-wind time series, power spectra, and discontinuity-angle distributions.
Key points
- The work focuses on constructing synthetic magnetic-field fluctuations resembling those observed in the solar wind.
- The method enforces nearly constant magnetic-field magnitude and zero divergence.
- Any specified power spectrum for component fluctuations can be imposed in the construction.
- Relative phases between two polarizations for each wave vector are chosen to minimize magnitude variance.
- A one-dimensional example reportedly reproduces observed solar-wind time series and power spectra.
- The construction also reportedly matches the distribution of angles associated with rapid magnetic-field changes (discontinuities).
