# POWER ANISOTROPY IN THE MAGNETIC FIELD POWER SPECTRAL TENSOR OF SOLAR WIND TURBULENCE

@article{Wicks2012POWERAI, title={POWER ANISOTROPY IN THE MAGNETIC FIELD POWER SPECTRAL TENSOR OF SOLAR WIND TURBULENCE}, author={Robert T. Wicks and Miriam A. Forman and Timothy S. Horbury and Sean Oughton}, journal={The Astrophysical Journal}, year={2012}, volume={746} }

We observe the anisotropy of the power spectral tensor of magnetic field fluctuations in the fast solar wind for the first time. In heliocentric RTN coordinates, the power in each element of the tensor has a unique dependence on the angle between the magnetic field and velocity of the solar wind (θB) and the angle of the vector in the plane perpendicular to the velocity (ϕB). We derive the geometrical effect of the high speed flow of the solar wind past the spacecraft on the power spectrum in…
