On the magnetic field line topology in solar active regions
Solar Physics, 1986The field lines of closed magnetic structures above the photosphere define a mapping from the photosphere to itself. This mapping is discontinuous, and the field line connectivity to the boundary can change discontinuously in response to continuous changes of field strength and direction, if field lines either end in a singular point of the field or ...

Fine-scan velocity and magnetic-field measurements in solar active regions
Solar Physics, 1971Fine scan (5″ × 5″ aperture) simultaneous Doppler and magnetograms have been obtained over solar active regions near the central meridian passage. Besides the mainly horizontal Evershed motion in sunspots, there appears a conspicuous descending motion over all active regions.

Statistical mechanics of velocity and magnetic fields in solar active regions
Solar Physics, 1985A statistical mechanics of the velocity and magnetic fields is formulated for an active region plasma. The plasma subjected to the conservation laws emerges in a most probable state which is described by an equilibrium distribution function containing a lagrange multiplier for every invariant of the system.

Methods for deriving the magnetic field in solar (radio) active regions
Astrophysics and Space Science, 2002In the present paper, in terms of the theory about the mechanisms of radio radiation, we have briefly classified, induced, summarized and reviewed the methods for deriving the magnetic field in the solar (radio) active regions.
