Hall currents generate a characteristic quadrupole out-of-plane
magnetic field at a
single X-line for a weak background guide-field and relatively
symmetric conditions
of plasma density and magnetic field strength across a reconnecting
current sheet.
This is observed as a bipolar perturbation of the out-of-plane magnetic
field (BM)
across the exhaust region as, e.g., reported...

Keynote
Recent simulations have revealed complex details of magnetic
reconnection than on the first glance
bring into question many established concepts in magnetic
reconnection. As an example, it is not
clear
whether the concept of the diffusion region, a theoretical construct
deeply ingrained into all things
reconnection, can be usefully extended to 3D reconnection. At the
same...

Oral
We have performed three-dimensional (3d)
magnetohydrodynamic simulations of
magnetic flux emergence in a model that spans the
convection zone and into the outer
solar atmosphere with the Bifrost code. This is a ``realistic''
model, in the sense that
the parameters and physical effects that control the
atmosphere can be used to
produce diagnostics that can be directly compared...
