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…
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…
Field lines twisting in a noisy corona: implications for energy storage and release, and initiation of solar eruptions
A. F. Rappazzo, M. Velli, G. Einaudi
We present simulations modeling closed regions of the solar corona threaded by a strong magnetic field where localized photospheric vortical motions twist the coronal field lines.…
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…
Shear Photospheric Forcing and the Origin of Turbulence in Coronal Loops
A. F. Rappazzo, M. Velli, G. Einaudi
We present a series of numerical simulations aimed at understanding the nature and origin of turbulence in coronal loops in the framework of the Parker model for coronal heating. A…
Diamagnetic and Expansion Effects on the Observable Properties of the Slow Solar Wind in a Coronal Streamer
A. F. Rappazzo, M. Velli, G. Einaudi +1
The plasma density enhancements recently observed by the Large-Angle Spectrometric Coronagraph (LASCO) instrument onboard the Solar and Heliospheric Observatory (SOHO) spacecraft h…
