Stability of tearing modes in presence of a velocity flow
Tearing modes, driven by plasma resistivity, collisional or collisionless, are one of the possible mechanisms leading to reconnection of initially antiparallel magnetic field lines. The theory of stability of a neutral sheet configuration with respect to tearing modes was developed including the presence of a plasma velocity flow and velocity gradients across the sheet. Consideration of the effects of a velocity flow are of noticeable importance, as the magnetic configurations which are encountered in space and where reconnection processes may occurare all accompanied by velocity flows. This is, for example, the case for the neutral sheet in the earth's magnetotail, the magnetopause boundary, and the boundaries between different sectors of the interplanetary magnetic field.
