# Coronal Heating Topology: the Interplay of Current Sheets and Magnetic Field Lines

## TL;DR

This study explores the magnetic topology and field line behavior in a nanoflare-heated solar corona, revealing anisotropic diffusion along current sheets and implications for particle acceleration and heat transport.

## Contribution

It introduces the concept of Current Sheet Connected (CSC) regions and analyzes their influence on magnetic field line diffusion in the corona.

## Key findings

- CSC regions form coherent structures around current sheets.
- Field line diffusion is strongly anisotropic along current sheets.
- Enhanced magnetic field intensities increase displacements in CSC regions.

## Abstract

The magnetic topology and field line random walk 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, extended around them. CSC field line random walk is strongly anisotropic, with preferential diffusion along the current sheets' in-plane length. CSC field line random walk 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.
