Energetics and 3-D Structure of Elementary Events in Solar Coronal Heating
G. Einaudi, R. B. Dahlburg, I. Ugarte-Urra +3
Parker (1972) first proposed that coronal heating was the necessary outcome of an energy flux caused by the tangling of coronal magnetic field lines by photospheric flows. In this…
Magnetic field line twisting by photospheric vortices: energy storage and release
A. F. Rappazzo, M. Velli, R. B. Dahlburg +1
We investigate the dynamics of a closed corona cartesian reduced magnetohydrodynamic (MHD) model where photospheric vortices twist the coronal magnetic field lines. We consider two…
Subresolution Activity in Solar and Stellar Coronae from Magnetic Field Line Tangling
A. F. Rappazzo, R. B. Dahlburg, G. Einaudi +1
The heating of coronal loops is investigated to understand the observational consequences in terms of the thermodynamics and radiative losses from the Sun as well as the magnetized…
Coronal Heating Topology: the Interplay of Current Sheets and Magnetic Field Lines
A. F. Rappazzo, W. H. Matthaeus, D. Ruffolo +2
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…
Multifractal Solar EUV Intensity Fluctuations and their Implications for Coronal Heating Models
Ana Cristina Cadavid, Yeimy J. Rivera, John K. Lawrence +3
We investigate the scaling properties of the long-range temporal evolution and intermittency of SDO/AIA intensity observations in four solar environments: an active region core, a…
"Ideally" unstable current sheets and the triggering of fast magnetic reconnection
Anna Tenerani, Marco Velli, Fulvia Pucci +2
Magnetic reconnection is thought to be the dynamical mechanism underlying many explosive phenomena observed both in space and in the laboratory, though the question of how fast mag…
