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…

Modeling of Condensations in Coronal Loops Produced by Impulsive Heating

Therese A. Kucera, James A. Klimchuk, Manuel Luna

We present the results of models of impulsively heated coronal loops using the 1-D hydrodynamic Adaptively Refined Godunov Solver (ARGOS) code. The impulsive heating events (which…

Are coronal loops projection effects?

Vadim M. Uritsky, James A. Klimchuk

We report results of an in-depth numerical investigation of three-dimensional projection effects which could influence the observed loop-like structures in an optically thin solar…

The Thickness of Electric Current Sheets and Implications for Coronal Heating

James A. Klimchuk, James E. Leake, Lars K. S. Daldorff +1

The thickness of current sheets is extremely important, especially as it relates to the onset of fast magnetic reconnection. Onset determines how much magnetic free energy can buil…
