Self-Consistent Heating of the Magnetically Closed Solar Corona: Generation of Nanoflares, Thermodynamic Response of the Plasma and Observational Signatures
Craig D. Johnston, Lars K. S. Daldorff, James A. Klimchuk +5
The energy that heats the magnetically closed solar corona originates in the complex motions of the massive photosphere. Turbulent photospheric convection slowly displaces the foot…

The nature of small scale EUV solar brightenings investigated as impulsive heating of short loops in 1D hydrododynamics simulations
A. Dolliou, J. A. Klimchuk, S. Parenti +1
Small (400 to 4000 km) and short lived (10 to 200 km) extreme ultraviolet (EUV) brightenings, detected by the High Resolution Imager EUV (HRIEUV), have been found to be ubiquitous…

Spatial and Temporal Distribution of Nanoflare Heating During Active Region Evolution
Biswajit Mondal, James A Klimchuk, Amy R. Winebarger +2
Nanoflares are believed to be key contributors to heating solar non-flaring active regions, though their individual detection remains challenging. This study uses a data-driven fie…
