A Model for Solar Coronal Mass Ejections
TLDR
In this article, a magnetic breakout model for the initiation of a solar coronal mass ejection (CME) was proposed, where reconnection between a sheared arcade and neighboring flux systems triggers the eruption.Abstract:
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 with previous models: (1) very low-lying magnetic field lines, down to the photospheric neutral line, can open toward infinity during an eruption; and (2) the eruption is driven solely by magnetic free energy stored in a closed, sheared arcade. Consequently, the magnetic energy of the closed state is well above that of the posteruption open state. The key new feature of our model is that CMEs occur in multipolar topologies in which reconnection between a sheared arcade and neighboring flux systems triggers the eruption. In this "magnetic breakout" model, reconnection removes the unsheared field above the low-lying, sheared core flux near the neutral line, thereby allowing this core flux to burst open. We present numerical simulations that demonstrate our model can account for the energy requirements for CMEs. We discuss the implication of the model for CME/flare prediction.read more

TL;DR: In this paper, the authors show that solar eruptions can be initiated in a single bipolar configuration with no additional special topology, and they show that an electric current sheet forms in the highly sheared core field of the magnetic arcade during its quasi-static evolution.

Magnetohydrodynamic simulations of the ejection of a magnetic flux rope
TL;DR: In this article, the authors simulate the whole life span of a flux rope from slow formation to rapid ejection and investigate whether magnetic flux ropes formed from a continuous magnetic field distribution, during a quasi-static evolution, can erupt to produce a CME.

Mass Loss Rates from Coronal Mass Ejections: A Predictive Theoretical Model for Solar-Type Stars
TL;DR: In this paper, a power-law relationship between surface-averaged magnetic fluxes and CME properties was found for the Sun, and it was generalized for use on other stars and an example prediction of the time evolution of wind/CME mass-loss rates for a solar-mass star was given.

TL;DR: In this paper, the authors investigated the processes leading to the catastrophic filament eruption and found that the filament slowly ascended at a speed of 0.1 km s-1 over 2 days before the eruption.

Disruption of Coronal Magnetic Field Arcades

TL;DR: In this paper, the magnetic field expands outward in a process that opens the field lines and produces a tangential discontinuity, leading to an impulsive release of magnetic energy, fast flows, and the ejection of a plasmoid.

TL;DR: In this article, a priori inequalities are defined which must be satisfied by the force-free equations, and upper bounds for the magnetic energy of the region provided the value of the magnetic normal component at the boundary of a region can be shown to decay sufficiently fast at infinity.
