On the Relationship Between Nanoflare Energy and Delay in the Closed Solar Corona
Shanwlee Sow Mondal, James A. Klimchuk, Craig D. Johnston +1
Determining the relationship between nanoflare energies and their delays is the key for understanding the physical mechanism of the events and the plasma response. Nanoflares analy…
Characterizing Nanoflare Energy and Frequency through Field Line Analysis
Shanwlee Sow Mondal, Lars K. S. Daldorff, James A. Klimchuk +1
We present a detailed analysis of a 3D MHD simulation of a subset of the magnetic flux in an active region. The simulation models the generation of nanoflares and response of the p…
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…
Filament Mass Losses Forced by Magnetic Reconnection in the Solar Corona
Craig D. Johnston, Lars K. S. Daldorff, Peter W. Schuck +4
Recent observations of the solar atmosphere in cool extreme ultraviolet (EUV) lines have reported the prevalence of coronal rain falling from coronal cloud filaments that are assoc…
Heating and cooling in stellar coronae: coronal rain on a young Sun
Simon Daley-Yates, Moira M. Jardine, Craig D. Johnston
Recent observations of rapidly-rotating cool dwarfs have revealed H line asymmetries indicative of clumps of cool, dense plasma in the stars' coronae. These clumps may be either…
