Magnetic Field Modeling of hot channels in Four Flare/CME Events
Tie Liu, Yingna Su, Xin Cheng +2
We investigate the formation and magnetic topology of four flare/CME events with filament-sigmoid systems, in which the sigmoidal hot channels are located above the filaments, and…
Direct and Inverse Cascades in the Acceleration Region of the Fast Solar Wind
Adriaan A. van Ballegooijen, Mahboubeh Asgari-Targhi
Alfvén waves are believed to play an important role in the heating and acceleration of the fast solar wind emanating from coronal holes. Nonlinear interactions between the dominant…
Heating and Acceleration of the Fast Solar Wind by Alfvén Wave Turbulence
A. A. van Ballegooijen, M. Asgari-Targhi
We present numerical simulations of reduced magnetohydrodynamic (RMHD) turbulence in a magnetic flux tube at the center of a polar coronal hole. The model for the background atmosp…
Nonlinear Force-Free Field Modeling of the Solar Magnetic Carpet and Comparison with SDO/HMI and Sunrise/IMaX Observations
L. P. Chitta, R. Kariyappa, A. A. van Ballegooijen +2
In the quiet solar photosphere, the mixed polarity fields form a magnetic carpet, which continuously evolves due to dynamical interaction between the convective motions and magneti…
The Spatial and Temporal Dependence of Coronal Heating by Alfven Wave Turbulence
M. Asgari-Targhi, A. A. van Ballegooijen, S. R. Cranmer +1
The solar atmosphere may be heated by Alfven waves that propagate up from the convection zone and dissipate their energy in the chromosphere and corona. To further test this theory…
Magnetohydrodynamic Modeling of the Solar Eruption on 2010 April 8
B. Kliem, Y. N. Su, A. A. van Ballegooijen +1
The structure of the coronal magnetic field prior to eruptive processes and the conditions for the onset of eruption are important issues that can be addressed through studying the…
