Zones with quasi-discontinuous magnetic connections in the photosphere and solar flares
The topological structure of active regions is related with flare brightening. (Mandrini et a!, 1991, 1993; Démoulin et ai, 1992, 1993, 1994).

| Sumario: | The topological structure of active regions is related with flare brightening. (Mandrini et a!, 1991, 1993; Démoulin et ai, 1992, 1993, 1994). In these works, we modeled the observed longitudinal magnetic field by means of a discrete number of sub-photospheric magnetic poles, and derived the magnetic topology taking into account the connections between these poles (source method, MF). We present here a new method (quasi-discontinuity method, MQD). It finds the regions above the photosphere where the connectivity of field lines changes drastically. |
