Self-consistent nanoflare heating in model active regions: MHD avalanches

ABSTRACT Straightened cylindrical models of coronal loops have been standard for decades, and shown to support nanoflare-like heating, but the influence geometric curvature in upon heating produced has not discussed depth. Heating, its spatiotemporal distributions, associated mechanisms responsible are discussed, compared with those from straightened a loop. Previously, magnetohydrodynamic avalanches generalized curved loops, be viable. From that study, is analysed Heating seen arise processes originally instigated, yet dominated, by magnetic reconnection, producing bursty, aperiodic nanoflares, dispersed evenly throughout corona, modest bias away footpoints. One novelty arising simultaneous independent occurrence events at disjoint sites along individual strands, anticipating some features recently ‘campfires’ Solar Orbiter. With view future refinements model inclusion additional physical effects, implications this analysis discussed.
