Dear all,<br>
<br>
our new paper accepted on ApJ analyzes the relationship between
magnetic<br>
field lines and current sheets in our nanoflare-heated model corona.<br>
It could be of particular interest to 1D/nanoflare modelers and moss
aficionados.<br>
<br>
Cheers,<br>

random walk (FLRW) properties of a nanoflare-heated and
magnetically confined corona are investigated in the reduced
magnetohydrodynamic regime. Field lines originating from current
sheets form coherent structures, called current sheet connected
(CSC) regions, which extend around them. CSC FLRW is strongly
anisotropic, with preferential diffusion along the current sheets’
in-plane length. CSC FLRW properties remain similar to those of
the entire ensemble but exhibit enhanced mean square displacements
and separations due to the stronger magnetic field intensities in
CSC regions. The implications for particle acceleration and heat
transport in the solar corona and wind, and for solar moss
formation are discussed.</span>
