Project details

The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non-magnetic forces like plasma pressure gradient and gravity can be neglected in the lowest order. This model assumption is called the force-free field assumption, as the Lorentz force vanishes.

A common assumption in modelling coronal solar flares is to assume the field is force-free, and adjust the field pitch to match local measurements of the photosphere field footprint. Such fields are called nonlinear force free fields.

In this project, we apply multiple-region relaxed MHD model, designed to describe the fractal fix of chaotic field lines, magentic islands, and flux surfaces in toroidal magnetic confinement, to describe a solar flare.
