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 such as …

This publication provides an overview of magnetic fields in the solar atmosphere with the
focus lying on the corona. The solar magnetic field couples the solar interior with the visible …

Abstract Knowledge regarding the coronal magnetic field is important for the understanding
of many phenomena, like flares and coronal mass ejections. Because of the low plasma …

Nonlinear force-free field (NLFFF) models are thought to be viable tools for investigating the
structure, dynamics, and evolution of the coronae of solar active regions. In a series of …

The magnetic field of the Sun is the underlying cause of the many diverse phenomena
combined under the heading of solar activity. Here we describe the magnetic field as it …

We compare six algorithms for the computation of nonlinear force-free (NLFF) magnetic
fields (including optimization, magnetofrictional, Grad–Rubin based, and Green's function …

Solar flares and coronal mass ejections are associated with rapid changes in field
connectivity and are powered by the partial dissipation of electrical currents in the solar …

Abstract The Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics
Observatory (SDO) provides photospheric vector magnetograms with a high spatial and …

The coronal magnetic field is an important quantity because the magnetic field dominates
the structure of the solar corona. Unfortunately, direct measurements of coronal magnetic …

Plasma in the Sun's hot corona expands into the heliosphere as a supersonic and highly
magnetized solar wind. This paper provides an overview of our current understanding of …
