A self-consistent nonlinear force-free solution for a solar active region magnetic field
M. S. Wheatland, S. Regnier
Nonlinear force-free solutions for the magnetic field in the solar corona constructed using photospheric vector magnetic field boundary data suffer from a basic problem: the observ…
Relationship between photospheric currents and coronal magnetic helicity for force-free bipolar fields
S. Regnier
The origin and evolution of the magnetic helicity in the solar corona are not well understood. For instance, the magnetic helicity of an active region is often about Mx$^…
Coronal Alfven speeds in an isothermal atmosphere I. Global properties
S. Regnier, E. R. Priest, A. W. Hood
Estimating Alfven speeds is of interest in modelling the solar corona, studying the coronal heating problem and understanding the initiation and propagation of coronal mass ejectio…
POLAR Investigation of the Sun - POLARIS
T. Appourchaux, P. Liewer, M. Watt +34
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the S…
Non-linear force-free field modeling of a solar active region around the time of a major flare and coronal mass ejection
C. J. Schrijver, M. L. DeRosa, T. Metcalf +14
Solar flares and coronal mass ejections are associated with rapid changes in field connectivity and powered by the partial dissipation of electrical currents in the solar atmospher…
Nonlinear force-free models for the solar corona I. Two active regions with very different structure
S. Regnier, E. R. Priest
With the development of new instrumentation providing measurements of solar photospheric vector magnetic fields, we need to develop our understanding of the effects of current dens…
