Abstract: |
Area asymmetries in the Stokes V profile of the Zeeman-sensitive Fe I
line at 630.25 nm shed light on gradients of velocity and magnetic
field along the photon path. We use that information on observations
of Hinode-SOT/SP of the quiet sun at different heliocentric angles to
further investigate turbulent field models in those regions. The
relationship between the asymmetry value and a correlation length
scale for the field strength in the framework of stochastic radiative
transfer for polarized light allows us to identify in the data
subresolution scales of change of the magnetic field. From these we
make a crude first attempt to determine the energy spectrum of the
turbulent magnetic field down to the km scale as a proof-of-concept of
the potential of this technique. |
