A Model for Solar Coronal Mass Ejections
We propose a new model for the initiation of a solar coronal mass ejection (CME). The model agrees with two properties of CMEs and eruptive flares that have proved to be very difficult to explain
MAGNETIC HELICITY GENERATION BY SOLAR DIFFERENTIAL ROTATION
Observations of sunspots, active regions, filaments, coronal arcades, and interplanetary magnetic clouds indicate that the Sun preferentially exhibits left-handed, negative-helicity features in its
Topological Evolution of a Fast Magnetic Breakout CME in Three Dimensions
We present the extension of the magnetic breakout model for CME initiation to a fully three-dimensional, spherical geometry. Given the increased complexity of the dynamic magnetic field interactions
The Mechanisms for the Onset and Explosive Eruption of Coronal Mass Ejections and Eruptive Flares
We have investigated the onset and acceleration of coronal mass ejections (CMEs) and eruptive flares. To isolate the eruption physics, our study uses the breakout model, which is insensitive to the
Slip-Running Reconnection in Quasi-Separatrix Layers
Using time dependent MHD simulations, we study the nature of three-dimensional magnetic reconnection in thin quasi-separatrix layers (QSLs), in the absence of null points. This process is believed to
Rotation of Coronal Mass Ejections during Eruption
Understanding the connection between coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs) is one of the most important problems in solar-terrestrial physics. We calculate the
Dynamics of coherent structures and transition to turbulence in free square jets
We report results of time‐dependent numerical simulation of spatially developing free square jets initialized with a thin square vortex‐sheet with slightly rounded corner‐regions. The studies focus
A Breakout Model for Solar Coronal Jets with Filaments
Recent observations have revealed that many solar coronal jets involve the eruption of miniature versions of large-scale filaments. Such "mini-filaments" are observed to form along the polarity
Formation and Stability of Helical Prominence Magnetic Fields
Abstract : We numerically simulated an initially bipolar magnetic field subjected to shear motions concentrated near and parallel to the photospheric polarity inversion line. The simulations yield
FORMATION AND EVOLUTION OF A MULTI-THREADED SOLAR PROMINENCE
We investigate the process of formation and subsequent evolution of prominence plasma in a filament channel and its overlying arcade. We construct a three-dimensional time-dependent model of a
