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…
Turbulent Coronal Heating Mechanisms: Coupling of Dynamics and Thermodynamics
R. B. Dahlburg, G. Einaudi, A. F. Rappazzo +1
Context. Photospheric motions shuffle the footpoints of the strong axial magnetic field that threads coronal loops giving rise to turbulent nonlinear dynamics characterized by the…
Nonlinear Dynamics of the Parker Scenario for Coronal Heating
A. F. Rappazzo, M. Velli, G. Einaudi +1
The Parker or field line tangling model of coronal heating is studied comprehensively via long-time high-resolution simulations of the dynamics of a coronal loop in cartesian geome…
Modeling the Galactic Center Nonthermal Filaments as Magnetized Wake
Russell B. Dahlburg, Giorgio Einaudi, T. N. LaRosa +1
We simulate the Galactic Center nonthermal filaments as magnetized wakes formed dynamically from amplification of a weak (tens of G) global magnetic field through the interactio…
