Quasi-Static Evolution, Catastrophe, and “Failed” Eruption of Solar Flux Ropes

The Helicial Flux Rope Structure of Solar Filaments

According to J. B. Taylor’s relaxation theory for magnetized plasmas, helical flux ropes should be the fundamental building blocks of magnetism in the solar atmosphere. Although flux ropes are clearly ejected from the Sun, there has been some controversy about whether they exist in the sun’s atmosphere before ejection. The issue is important because of the need to understand how eruptions are i...

Catastrophic eruption of magnetic flux rope in the corona and solar wind with and without magnetic reconnection

It is generally believed that the magnetic free energy accumulated in the corona serves as a main energy source for solar explosions such as coronal mass ejections (CMEs). In the framework of the flux rope catastrophe model for CMEs, the energy may be abruptly released either by an ideal magnetohydrodynamic (MHD) catastrophe, which belongs to a global magnetic topological instability of the sys...

Reconnecting flux-rope dynamo.

We develop a model of the fluctuation dynamo in which the magnetic field is confined to thin flux ropes advected by a multiscale model of turbulence. Magnetic dissipation occurs only via reconnection of the flux ropes. This model can be viewed as an implementation of the asymptotic limit R_{m}-->infinity for a continuous magnetic field, where magnetic dissipation is strongly localized to small ...
