The coronal magnetic configuration of an active region typically evolves quietly for a few days before becoming suddenly eruptive and launching a coronal mass ejection (CME). The precise origin of the eruption is still under debate. The loss of equilibrium, or an ideal magnetohydrodynamic (MHD) instability such as torus instability are among the several mechanisms that have proposed to be responsible for the sudden eruptions. Distinct approaches have also been formulated for limited cases… Expand

THE APPARENT CRITICAL DECAY INDEX AT THE ONSET OF SOLAR PROMINENCE ERUPTIONS
A magnetic flux rope (MFR) embedded in a line-tied external magnetic field that decreases with height as-z n is unstable to perturbations if the decay index of the field n is larger than a criticalExpand

We report on three-dimensional (3D) Magnetohydrodynamic (MHD) simulations of recurrent eruptions in emerging flux regions. We find that reconnection of sheared fieldlines, along the polarityExpand
Initiation of Coronal Mass Ejections by Sunspot Rotation
Abstract We report observations of a filament eruption, two-ribbon flare, and coronal mass ejection (CME) that occurred in Active Region NOAA 10898 on 6 July 2006. The filament was located South of aExpand

Statistical Analysis of Torus and Kink Instabilities in Solar Eruptions

What are the physical mechanisms of eruptions and CMEs
Abstract CMEs are due to physical phenomena that drive both, eruptions and flares in active regions. Eruptions/CMEs must be driven from initially force-free current-carrying magnetic field. TwistedExpand
Decoding the Pre-Eruptive Magnetic Field Configurations of Coronal Mass Ejections
A clear understanding of the nature of the pre-eruptive magnetic field configurations of Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting solar eruptions. OnlyExpand
Solar filament eruptions and their physical role in triggering Coronal Mass Ejections
Solar filament eruptions play a crucial role in triggering coronal mass ejections (CMEs). More than 80% of eruptions lead to a CME. This correlation has been studied extensively during the past solarExpand
